22.   Write the equation for the vertical line that contains point E(10, –3).

lukebluefive · Answer

Vertical lines are of the form:
$$x = constant$$
Point coordinates are usually arranged in the following way:
$$(x, y)$$
So the vertical line that contains the point (10, -3) must have the following equation:
$$x = 10$$
