math question

y=-5x+4

I meant that I need it in standard form....thanks for your help though
/_\

go on google and type "perpendicular of y=5x+4" you should get the answer
i also use a site called wolframalpha.com just type in your math problem and it will give you all possible answers.

I'm still stuck....thanks for your help but I'm not getting what I need..... /: :0

Lis@:

what is an equation perpendicular to y=5x+4

Hi Lis
1. What is the gradient of y=5x+4
2. How do you know if 2 lines are perpendicular ? (m ₁*m ₂ = -1
3. What is the gradient of a line perpendicular to y=5x+4
4. What is the equation of a line that is perpendicular to y=5x+4 (There are lots of answers, the one with a y intercept of 0 might be a smidge easier to rearrange.)
5. Take it all to the left side and put equal to 0 and then you are finished.

Try these steps and tell us when you get stuck.
