Question 159950: Determine whether the graphs of the pair of lines are parallel.
x+12=y
y-x= -8
What is the slope of the line x+12=y??? (type N if the slope is undefined)
What is the slope of the line y-x= -8???
Are the graphs of the given equations parellel?

You can put this solution on YOUR website!
Put your equations into slope-intercept form, y=mx%2Bb, where
the slope is m and the y-intercept is b.
1.y=x%2B12
This equation is already in slope-intercept form.
m%5B1%5D=1
2.y-x=-8
2.y=x-8
m%5B2%5D=1
Parallel lines have equal slopes.
Yes, the two lines are parallel.
