Graphing Linear Equations Review

3 key concepts

1
The equation for a linear equation is y = mx + b, where m represents the slope and b represents the y-intercept.
2
Slope is calculated by finding the change in y divided by the change in x, and a positive slope means moving up and right from a given point.
3
When graphing y = x + 2, the y-intercept is 2 and the slope is 1, which can be written as 1/1.
