Write in y=mx+b form the line perpendicular to 5x-y=2 passing through (10,-2)
Answered by L.Bianchessi
Solve for y for the given equations. Putting it in y=mx+b form. Then do the negative reciprocal of the slope from the given equation.
After that use the point slope formula to calculate the new equation using the given point and your new slope.
Do you get it?
Answered by Missy
I got -y=-5x+2 but I am confused on the actual math part. To get rid of the - on the y do I do y=1/5x+1/2?
Answered by L.Bianchessi
Oh, you just divide the negative to each side and get y=5x-2.

Then use y-y1=m(x-x1)
y-(-2)=-1/5(x-10)
Then solve.

Oh and the answer would be y=-1/5x
Answered by Missy
so just to check is the answer y=-1/5x? Thanks for all your help by the way.
