I need help solving this problem! It’s from the SAT!!

8/3

Explanation:

equation of f(x) = -3x +3

slope of g(x) is the negative reciprocal of the slope of f(x)

slope of g(x) = 1/3

let us find the y-intercept of g(x) using the point (1,3)

y= mx + b

3 = 1/3 (1) + b

3-(1/3) = b

8/3 = b

g(x) = 1/3x + 8/3

g(0) = 8/3

( g(0) is nothing but the y-intercept of function g(x))

answer:

is this a serious question? let me know!
