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...

Given two points on a line, this video shows how to write the linear equation in point-slope form, slope-intercept form, and standard form. First, Sal reviews each of these forms, then calculates the slope, writes the equation in...

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.

Given two points on a line, write an equation in point-slope form. But what's the slope? Oh, you have to figure out the slope first. That can be done given two points. Just use the rise over run slope formula. This isn't so hard after...

Given the coordinates for a point on a line and given the slope of that line, write an equation in point-slope form. Really, all that needs to be done is to use the formula for point-slope form and plug in the values.

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...

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 =...

This video shows how to graph a linear equation in standard form. He shows three different examples where he changes each equation into slope-intercept form and graphs it. One of the examples is a line with a negative slope, one is a...
