Learn linear equations in slope-intercept form with Khan Academy's free online educational resources.

A line that's flat has a slope of 0. If a line goes up as you move to the right, it has a positive slope. The steeper it is, the bigger the slope. If a line goes down as you move to the right, it has a …

First of all (I'm sure you already did this :) ), given the points (1,4 --> where 1 is X1 and 4 is Y1) and (2,2 --> where 2 is X2 and 2 is Y2), we need to find the slope using the slope formula (Y2 …

Learn how to find the slope of a line in this Khan Academy video.

Use either ordered pair along with the slope to build the equation in the format: y = mx + b. Substitute the x and y coordinates for x and y, respectively, in the above equation. Then …
