Points on a Line and Slope of a Line

Investigate the different types of slope using graphs and ordered pairs. Scholars use the slope formula to determine the slope of a line between two points. Includes examples with a slope of zero and with no slope. The lesson follows a...

This video explores the following problem: Write the equation of a line in slope-intercept form, given a point and an equation of a line that is perpendicular to the line. First the slope is determined based on the known relationship...

The instructor uses a computer graphing program to illustrate how a line changes slope by manipulating the slope values in the equation. He also manipulates the y-intercept value to see where the line crosses the y-axis.

Use the slope formula to find the missing coordinate. You've been given all the needed information to solve this problem. So all you need to do is plug in the values and solve for the missing variable value.

Slope-intercept form ... perhaps it has something to do with slope and intercepts? An easy-to-use interactive lets users adjust the locations of two points on a line. The interactive automatically updates the slope-intercept form of the...

This problem has many steps involved. Finding equations and rearranging equations. Finding slope and getting the opposite reciprocal of a slope. Finding intercepts. There's a lot to do to solve this problem. It's not so difficult, it...

The instructor demonstrates how to verify that a given point does or does not lie on the line of a given equation. She draws a graph (the axis lines need arrow ends) and plots the given linear equation. She then plots the coordinate...

There are many pieces and many parts to this problem. It seems simple enough to write an equation in slope-intercept form. In this problem, there is a given table of values and information from this table is used to get an equation...

If you are given the value for slope (m), and the value for the intercept (b), all you need to do is remember what the slope-intercept form looks like. Y=mx+b. Then you just have to plug the given values into the slope-intercept line of...

Given two points on a line, find the value for slope using the rise over run formula. Then find the y-intercept by plugging one of the point values into the equation of a line. Finally, put these values into the equation of a line y =...
