Question

(4,15) (8,9) find the slope

Answer 1

Answer:  The slope is -3/2

Step-by-step explanation:

To find the slope, find the difference in the y coordinates and divide it by the difference in the x coordinates.

y coordinates;   9 - 15 = -6

x coordinates : 8 - 4 = 4  

Slope:     -6/4  =   -3/2

Answer 2

Answer:

$\frac{15-9}{4-8}= \frac{6}{-4} = -\frac{3}{2}$
