Question

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

Function A

F(x) = 2x − 8

Function B


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.

Answer 1

A.) Slope of function B = 2 * the slope of Function A.

Function B shows the slope of 4 while the slope of function A is shown as 2 therefore it'd be 2 times the slope. Hence, option A.

Answer 2

Slope of Function B = 2 x Slope of Function A.

Explanation:

The graph of Function B shows its slope to be 4 units up for 1 unit to the right, so 4.

The equation for Function A shows its slope to be the coefficient of x, so 2.

___

4 is 2 times 2, so ...

the slope of Function B is 2 times the slope of Function A.
