The equation below represents function a and the graph represents function b: function a f(x) = x − 9 function b (image) which equation best compares the slopes of the two functions? a) slope of function b = 2 x slope of function a. b) slope of function a = slope of function b c) slope of function a = 2 x slope of function b d)slope of function b = − slope of function a

We have the equation for function A. Is is a line, already written in the form . In these cases, the slope of the line is . So, the slope of function A is 1.

As for function B, we have to pick two of its graph's point, say and compute the slope as follows:

We can see that the function passes through the points and [/tex] (1,1) [/tex]. So, its slope is

So, the slope of function A is 1, and the slope of function B is 2.

This means that the first option is correct.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
