Identify the SLOPE (m) and the Y-INTERCEPT (b).
To find the y-intercept, find the point where the line crosses the y-axis.
To find the slope, pick two points on the line that are easy to read.
Then see how many units up or down and how many units right or left you need to go from the first point to the second point. Divide the up or down (the rise) by the right or left (the run). That is the slope.
The equation is
y = mx + b,
where m = slope and b = y-intercept.
