Question

Choose the equation of the horizontal line that passes through the point (-8, -7).

y = -8

y = -7

x = -8

x = -7

Answer 1

slope intercept form is y=mx+b, but for a horizontal line, the slope = m = 0
so the y intercept, y=b = the point and = the equation. Which also happens to be the y value in the (-8, -7).

Answer 2

y = ?
