Question

Determine if the lines are parallel, perpendicular or neither:
1. x + 4 = y and y – x = -3

Answer 1

neither

Explanation:

the second isnt a line

Answer 2

parallel

Explanation:

they have the same slope

look at them in terms of y=mx+b

first equation has slope of 1 (y=x+4)

second equation has slope of 1 also (y=x-3)
