Answer: 6
Step-by-step explanation:
Slope is found by doing:
[tex]\frac{y_1 - y}{x_1 - x}[/tex]
(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)
Let us say that (x1,y1) is (3,18)
And (x,y) is (5,30)
[tex]\frac{18 - 30}{3 - 5} = \frac{-12}{-2} = 6[/tex]
