Find the slope of the line parallel to the line graphed.
a) -1
b) 0
c) 1
d) undefined

The slope of the parallel line (which has the same slope as the referenced line) line would be undefined, as vertical lines are undefined. Let's test this.

Slope is y2-y1/x2-x1. We'll use the points (2,-5) and (2,5)
5-(-5)/2-2 simplifies to 10/0. Since you can't divide by zero, this is undefined.

:)

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
