Answer:
X=4
Step-by-step explanation:
The line that is perpendicular to y
= −3 is a horizontal line, because horizontal and vertical lines (x- and y- axes for example) are perpendicular. Therefore, this line will take the form x
=n where n is the x
-coordinate of the point passed through. The x
-coordinate of the given ordered pair (4,−6) is 4, so the equation must be x=4
