Question

Find the slope of the line through each pair of points.

9) (17,-6), (-11,7)
10) (3, 4), (-4,-5)
11) (-20, 14), (17, 15)
12) (11, -18), (-1, -7)

Helpppp

Answer 1

10 (3,4),(-4,-5) I think I had this question

Answer 2

Slope = (y2-y1) / (x2-x1)

9) (7 - -6)/(-11- 17) = 13/-28

10) (-5-4)/(-4-3)= -9/-7

11) (15-14)/(17- -20) = 1/37

12) (-7 - -18) /(-1 -11) = 11/-12
