Question

Choose the equation of the horizontal line that passes through the point (-2,-1).

A.) y = -1

B.) y = -2

C.) x = -2

D.) x = -1

Answer 1

A.) y = -1

Explanation:

The equation of a horizontal line is ...

y = constant

To make that line go through the point (x, y) = (-2, -1), the constant must match the y-coordinate of the point: -1.

y = -1
