Question

Identify the function shown in this graph

Answer 1

C. y = -3x - 3

Explanation:

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

m = (6 - -3)/(-3 - 0)

m = (9)/(-3)

m = -3

then

y = -3x + b

6 = -3(-3) + b

b = -3

so

y = -3x - 3

Answer 2

C

Explanation:

Because the gradient is -3 and the y intercept is -3. Therefore -3x-3 is the answer.
