Answer 1

slope = -1.75

Explanation:

If there are two points on a coordinate plane with point (x1,y1) and (x2,y2) then

slope of those two points are

slope = (y2-y1)/(x2-x1)\

________________________________________________

Given

points (1,9) and (-3, 16)

thus, slope = (16-9)/ (-3 -1)

slope = 7/-4 = -7/4 = -1.75

Thus, slope is -1.75
