Question 272443: Determine whether the graphs of the lines are parallel.
x + 13= y
y-x = -9
What is the slope line for x + 13?
What is the slope line for y - x = -9

You can put this solution on YOUR website!
You have two equations that need to put into y=mx+b format.
.
y = x + 13
y = x - 9
.
The slope of both lines is 1, so they may be parallel or the same line.
They have different y-intercepts, so they are not the same line.
So they are parallel.
