Find the slope between the two points: (9,9) and (12,15)

grandymaker [24]

The slope formula is $\frac{Y2-Y1}{X2-X1}$ . For the two points, $(x,y)$ . You can pick any of the Y and X from these two points, but only once. $\frac{9-15}{9-12}$ = $\frac{-6}{-3}$ = 2 or $\frac{15-9}{12-9}$ = $\frac{6}{3}$ = 2 and both will equal to. The answer for the slope is 2.
