For the graph x = 12 find the slope of a line that is perpendicular to it and the slope of a line parallel to it.

Step-by-step explanation:

A line whose equation has the form x = 12 is a VERTICAL line whose slope is undefined (because x does not change and division by zero is undefined).  Another line parallel to this one has the same slope:  "undefined."

Another line perpendicular to x = 12 has slope m = 0.

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.
