slope = -1.75

Step-by-step 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

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
