y = -8

Explanation:

Slope intercept form is y = mx + b where m = slope, and b = yintercept (0, b).

When a line is in the form y = -5, it has m = 0, therefore the line is a horizontal line. Horizontal lines have different values of x, but the same y-value. The line passes through points such as (-1, -5), (0, -5), (2, -5), (4, -5).

A line that is parallel has the same slope: m = 0. It is also a horizontal line. To pass through (-1, -8) the line must be y = -8
