Question

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

Function A
f(x) = 6x – 1

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

Slope Function A = 2 x slope of Function B

Explanation:

Function B

y = 3x + 1

y = mx + b The line crosses at 1 that the b. The slope is 3. If you start at (0,1) and go up three and right 1 you will be back on the line. Rise over run

3/1 = 3

The slope of A is 6 and the slope of B is 3. The slope of A is 2 times the slope of B

2(3) = 6
