Given f(x) and g(x) = k· f(x), use the graph to determine the value of k

if g(x) = k•f(x), then we know g(-3) = k•f(-3).  I'd pick x=-3 because of the two dots on the graph, which tell us:

    g(-3) = -2   and   f(-3) = 1

So, -2 = k•1 or k = –2

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
