Question

Write the equation of a line that is:

Perpendicular to y=3/2x and whose y intercept is 5

parallel to y=2x+7 and which passes through (-2,5)

Answer 1

For the first one i got y=-2/3x+5
The second one: y=2x+9

Answer 2

Perfect! :)

Answer 3

But, the last equation when i plug in two points it doesn't make sense

Answer 4

it doesnt match up with 2x + 7

Answer 5

if you plug in 5 for y and -2 for x into your answer equation
5 = 2(-2) + 9
5 = -4 + 9
5 = 5 --> true

so it works ^_^

Answer 6

they don't care about the 2x+7 one, that was just there for you to get the slope :)

Answer 7

Oh, so not necessarily they need to match up with the original one

Answer 8

mhmm ^_^

Answer 9

Thanks
