Question

The graph of a line passes through the two points (-2, 1) and (2, 1). What is the equation of the line written in general

form?
Oy - 1= 0
Ox-y+1 = 0
OX+ y - 1= 0​

Answer 1

y - 1 = 0.

Explanation:

First off, we need to find the slope between the two points. That would be (1 - 1) / (2 - -2) = 0 / 4 = 0.

So, we would have an equation y = mx + b, where m is the slope and b is the y-intercept. Since the slope is 0, we have y = 0x + b, or y = b.

If you examine the coordinates, y always equals 1. So, b = 1, and y = 1.

y = 1

y - 1 = 0.

Hope this helps!
