Common Core Aligned Resources for 8.F.A.3
Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. For example, the function A = s^2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.

Drawing Graphs Using Xy Tables
8 mins 7th - 9th CCSS: Adaptable
New ReviewWhat does a linear equation look like in a table? A video lesson practices graphing linear equations by making an input-output table. The instructor emphasizes the pattern in the table and relates that to the graph of the function.
Gradient of a Line
9 mins 7th - 9th CCSS: Adaptable
New ReviewSteepness, gradient, and slope all refer to the same feature of a line. Young scholars watch and rewatch a video lesson to build a solid understanding of the relationship between the rise compared to the run of a line. Examples include...
Drawing Graphs Using Gradient and Intercept
4 mins 7th - 9th CCSS: Adaptable
New ReviewHelp mathematicians see lines from equations as they learn the patterns in the equations. An instructional video describes the steps to graphing a linear function. All equations begin in slope-intercept form and result in a line with...
Horizontal and Vertical Lines
3 mins 7th - 9th CCSS: Adaptable
Build a strong understanding of graphing and writing equations of horizontal and vertical lines. Pupils watch as the lesson instructor explains how to graph horizontal and vertical lines from an equation. She then gives individuals an...
End-of-Module Assessment Task: Grade 8 Module 5
8th CCSS: Designed
Give your class a chance to show how much they've learned in the module with an end-of-module assessment task that covers all topics from the module including linear and non-linear functions and volumes of cones, cylinders, and spheres.
Graphs of Linear Functions and Rate of Change
8th CCSS: Designed
Discover an important property of linear functions. Learners use the slope formula to calculate the rates of change of linear functions. They find that linear functions have constant rates of change and use this property to determine if...
