a. x - y = 1
b. -x + y = -1
c. -x + y + 1 = 0
d. x - y - 1 = 0
pls help asap !!!

Answer 1

Plug in numbers.

Explanation:

using the equation of a line, y=mx+b, m is slope and b is the y-intercept. y and x are the coordinates. So graph the line first. It has a slope of one and the y-intercept is -1. Then plug in numbers for the equation. Make sure they are reasonable.
