Find the equation of the line perpendicular to  y=−2 that passes through the point (4,  −2).

Step-by-step explanation:

the line

is a horizontal line on the -2 of the y-axis (for any x value, the y value is always -2).

Thus since is a horizontal line, a perpendicular line to a horizontal line has to be a vertical line.

Now, we want this vertical to pass through the point:

.

This means that the only option we have is the line:

because this is the equation of a vertical line sitting on the x = 4.

This can be better visualized in the attached image. where the red line is and the dotted blue line is

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450
