Question

A line passes through the points (1, 4) and (3,-4). Which is the equation of the line?

y=-4x+8
y=-2x + 6
y=-3x+2
y = 2x + 2

Answer 1

y = 4

Explanation:

The two given points both have the same y-value, so the line through them is a horizontal line. None of the answer choices is correct for the points given here.
