A relation is a set of inputs and outputs, often written as ordered pairs (input, output). We can also represent a relation as a mapping diagram or a graph. For example, the relation can be represented as:
Use the slope formula.
Subtract the y-coordinates.
Subtract the x-coordinates in the same order.
Divide the difference in y by the difference in x.
slope = m = (y2 - y1)/(x2 - x1)
slope = (5 - 7)/(-2 - (-1)) = -2/(-1) = 2
slope = 2
