What is the relationship between the lines with the following equations? 2x+8y=16 y=4x+7

1 answer:

6 0

They are perpendicular because when you change 2x+8y=16 to slope intercept form it becomes y= -1/4x+2 and the slope (-1/4) is the negative reciprocal of 4, which is the slope for your other equation.

Please comment if you have any questions :)
