👉 Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph...

In this lesson, students are taught to organize the data, create a frequency table, and determine the intervals for the number line. By placing dots on the graph to represent each data point, students can visually analyze and compare the...

In this video you will learn how to solve and graph inequalities. When solving inequalities you will use the same inverse operations as solving equations. The difference will be when you multiply or divide by negative numbers you switch...

In this video, the teacher explains how to solve take-apart problems using a bar graph. The example given is about children choosing between playing inside or outside for recess. The teacher demonstrates how to create a bar graph, label...

👉To solve a system of equations means to obtain a common x-value and a common y-value that makes the each of the equation in the system true. To solve a system of equations by graphing means to obtain the point of intersection (if any)...

In this video series I show you how to graph and order numbers. It is important when graphing and ordering numbers that we have all of our numbers simplified and written in the same form. We then can arrange the numbers from least to...

Learn how to graph a horizontal parabola. A parabola is the shape of the graph of a quadratic equation. A parabola is said to be horizontal if it opens to the left or opens to the right. A horizontal parabola results from a quadratic...

In this video, the teacher shows students how to represent data on a number line by creating a histogram. He explains the concept of bins and intervals, and demonstrates how to label and organize data points in a histogram.

To create a bar chart or histogram using ggplot is easy. Bar charts (or bar graphs) are used to visualise a single categorical variable. Histograms are used to visualise a single numeric variable. Ggplot2 is a powerful package used for...

👉Learn how to solve a system of linear equations from a word problem. A system of equations is a set of more than one equations which are to be solved simultaneously. A word problem is a real world simulation of a mathematical concept....

In this lesson, students learn how to find the total number of cans on a shelf and the total number of customers in a business by analyzing patterns using tables and graphs. They discover that sequences with quadratic growth have a...

In this lesson, students learn how to represent the solution set of an inequality on a number line. They review the concepts of variables, inequalities, and number line representations. Through a step-by-step process, students solve an...

The video is a lecture presentation on solving quadratic inequalities. The speaker begins by reviewing inequality symbols and explains how they provide a range of values rather than a single answer. The speaker then explains the process...

In this lesson, students will learn how to identify a proportional relationship by analyzing a graph. They will understand that a proportional relationship exists when an input is multiplied by a constant to create an output. They will...

👉 Learn about graphing absolute value equations. An absolute value equation is an equation having the absolute value sign and the value of the equation is always positive. The graph of the parent function of an absolute value equation is...

👉 Learn how to graph piecewise functions. A piecewise function is a function that has more than one sub-functions for different sub-intervals(sub-domains) of the function's domain. To graph a piecewise function, we graph the different...

In this video, the teacher explains how to find solutions to a problem involving the assembly of bicycles and scooters using linear inequalities and graphing on a coordinate plane. The teacher demonstrates how to interpret the context of...

👉 Learn how to reflect points and a figure over a line of symmetry. Sometimes the line of symmetry will be a random line or it can be represented by the x or y-axis. Either way when reflecting a point and or figure over the line of...

In this lesson, students will learn about vertical translations of linear equations. They will explore how these translations affect the graph and algebraic representation of the equations. By understanding the similarities and...

This video helps you explore graphs and commits in SourceTree. This clip is from the chapter "Rebasing" of the series "Complete Git Guide: Understand and Master Git and GitHub".This section explains the process of rebasing. It also...

Visualize one categorical and one numeric variable If you are interested in using R programming to visualize your data, then you have come to the right place. Ggplot is a fantastic package that can be used to create plots and graphs to...

Data visualisation is easy when you use ggplot. Ggplot2 is package and forms part of the tidyverse group of packages in R. Ggplot is used to create amazing plots and graphs. In this video I talk you though how to visualise two numeric...
