Answer: slope = -1.5

Step-by-step explanation:

Slope of the line that passes through (−9,8) and (−21,10) is calculated by change in y/change in x

= y2 - y1/ x2 - x1

Locate the coordinates points

X1 = -9, x2 = -21

y1= 8, y2 = 10

Slot the values into the formula

Slope = 10 - 8/ -21 - (-9)

=18/ -21 + 9

=18/ -12

Slope = -1.5

I hope this helps.
