X - y = 0

A, B, C, or D

D

Step-by-step explanation:

Using the equation y = mx + b.

m represents the slope

b represents where the line crosses the y axis.

We can attempt to set up the equation given in the same way.

x - y = 0

Add y to both sides and the 0 can drop out.

x = y

This is also equal to:

y = x

In this equation the m is equal to 1 and the b is equal to 0.

Taking this into account the answer is D.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
