Question

The x- and y- axes of the coordinate plane form four right angles. The interior of each of the right angles is a quadrant of the coordinate plane. What is the equation for the line that contains the angle bisector of Quadrants 1 and 3?

Answer 1

y = x

XPLANATION:

To find the equation for the line that contains the angle bisector of Quadrants 1 and 3 we have:

The equation is:

y = x
