Question

5. Write the equation of the line.

a. Point= (-3,3), parallel to y=0


b. Point= (5,-2), perpendicular to x=0

Answer 1

a. y = 3.

b. y = -2.

Explanation:

a. Parallel to y = 0 means parallel to the x- axis ( y = 0 is the x axis). The equation will be of the form y = something.

As it passes through the point (-3,3) it must therefore be y = 3.

b. Perpendicular to x = 0 means perpendicular to the y axis so the equation will be y = -2 (because it passes through (5, -2).
