Answer:

D) slope of function A is -2, function B is 4

Explanation:

you can see from the equation, y=-2x+1, that the slope (or rate of change) is -2 because it is the coefficient of the 'x' term

to get the slope of Function B we can use the slope formula:

slope =
((y-y))/((x-x))

using points (1,1) and (3,9) we get:

slope = (9-1)/(3-1)

= 8/2 or 4
