Question

What is an equation of the line that passes through the points (7, 4) and ( -5, 4)?

Answer 1

y = 4

Explanation:

To find the slope, you plug the coordinates into the slope formula.

y2 - y1/ x2 - x1

= 4 - 4/ -5 - 7

= 0

The slope is 0.

To find the y-intercept, y = 0x + b

4 = 0(7) + b

4 = 0 + b

4 = b

The equation is y = 4
