Determine whether the graphs of the given equations are parallel, perpendicular, or neither
y=x+11
y=-x+2

a. parallel
b. perpendicular
c. neither

Keywords

parallel, perpendicular, graphing, linear equation, slope, lines

we know that

If two lines are perpendicular, then the product of their slope is equal to minus one

so

If two lines are parallel, then their slope are equal

In this problem we have

--------> linear equation A

the slope is

 --------> linear equation B

the slope is

Find the product

---------> the lines are perpendicular

therefore

the answer is the option B

Perpendicular

using a graphing tool

see the attached figure

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis
