Question

The equation below represents Function A and the graph represents Function B:

Function A

f(x) = x – 9

Function B

graph of line going through ordered pairs negative 1, negative 3 and 2, 3

Which equation best compares the slopes of the two functions?
Slope of Function B = 2 x Slope of Function A.
Slope of Function A = Slope of Function B
Slope of Function A = 2 x Slope of Function B
Slope of Function B = – Slope of Function A
