Is -48x plus y equals 7 perpendicular to -8x plus 6y equals 7?

Answer 1

Use the Formula Y=mx + b

-48x + y = 7 -8x + 6y = 7

~Subtract -48x ~Subtract -8x

You now get y= 48x + 7 You now get 6y= 8x + 7

~ Divide 6 by each # on the opposite side. The slope (m) is 48/1

You now get y= 4/3x + 7

The slope (m) is 4/3

In order to be perpendicular you need to have a negative (opposite reciprocal slope). 48/1 and 4/3 are NOT negative reciprocals and thus are NOT perpendicular.
