the equation 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

   Slope of Function B = 2 x Slope of Function A

Step-by-step explanation:

step 1

Find the slope of the function A

we have

This is the equation of the line into point slope form

where m is the slope

b is the y-intercept

therefore

The slope of the function A is

step 2

Find the slope of the function B

we have the points

(-1,-3) and (2,3)

The slope m is equal to

step 3

Compare the slopes

therefore

The slope of the function B is two times the slope of the function A

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
