Write a rule to describe the function shown. x y −3 9 −1 3 0 0 3 −9 y = 3x y = −3x y equals start fraction one over three end fraction x y equals negative start fraction one over three end fraction x

y = -3x  

Step-by-step explanation:

(a) Slope

y = mx + b

Choose points (-3, 9) and (3, -9)

m = (-9 - 9)/(3 – (-3))

m = -18/(3 + 3)

m = -18/6

m = -3

(b) y-intercept

y = mx +b

Choose point (0,0).

0 = 0 + b

b = 0

(c) Equation of line

y = mx + b

y = -3x

i dont get the question
