The points (-15, -3) and (-7, -1) both lie on the graph of the linear function y =f(x). What is the rate of change of f(x) with respect to x? F: 4
H: 1/4
G: -4
J: - 1/4

Step-by-step explanation:

The rate of change, m, is defined as

m=(y2-y1)/(x2-x1), in this case we have points (-15,-3) and (-7,-1) so

m=(-1+3)/(-7+15)

m=2/8

m=1/4

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
