Question

What is the equation of the line shown?

x + y - 2 = 0
x - y - 2 = 0
x + y + 2 = 0

Answer 1

x+y+2=0 when you get x+y all by themselves you're left with x+y=-2 which according to the equation y=mx+b would mean that your slope is negative as well as your y intercept. the y intercept being the -2 on the other side and the slope of a -1 next to the x. so if you rework this solution it would be exactly y=-x-2 which reversed would be x+y+2=0
