Question

Find the equation of a line perpendicular to the y-axis passing through thepoint (4,7)

Answer 1

Y = 7

Explanation:

The equation is Y = 7 because the line is horizontal; it is not at an angle.

The slope is 0, so you could do it as Y = 0 + 7, but that would be redundant.

This equation works for both standard form and slope intercept form.
