Question

passing through (4,-2) and perpendicular to x=5/4y-2. Write in slope intercept form.


For my answer i have y=-4/5x+6/5 is this correct?

Answer 1

Answer 2

x=5/4y-2

x+2=5/4y

5/4y = x+2

y = 4/5x + 2(4/5)

y = 4/5x + 8/5

Answer 3

the slope of y = 4/5x + 8/5 is 4/5

so the slope of x=5/4y-2 is also 4/5

Answer 4

the perpendicular slope would be -5/4 because you flip the fraction and the sign of 4/5

Answer 5

so your answer will have a slope of -5/4 not -4/5

Answer 6

the original slope was 5/4 not 4/5

Answer 7

you first need to solve for y to get the slope

Answer 8

5/4 is not the original slope

Answer 9

soo it would then be -4/5 for perp wouldn't it?

Answer 10

-5/4 for the perp

Answer 11

4/5 is the original slope

Answer 12

okay
