Question

Write an equation of a horizontal line passing through the two points (-2,-3) and (2,-3)

Answer 1

Explanation:

hello :

Use the point-slope formula.

y - y_1 = m(x - x_1)

m=0 ( horizontal line) and x_1 = 2 y_1 = -3

y-(-3) = 0(x-2)

y+3=0 is an equation

Answer 2

y = -3

Explanation:

The first thing you should know is that a horizontal line always has a slope of 0. When the line is horizontal, the y coordinate never changes. So, your equation in slope intercept is:

y = -3
