Question

Find the equation of the perpendicular line to each of the following that passes through the point indicated.
4x + 5y = - 40 passing through the point (-1, 3)
Answer

5x - 4y = -17

5x + 4y = 17

5x + 4y = -17

-5x + 4y = 17

Answer 1

you found it :D

Answer 2

well first

4x + 5y = - 40
sfy to get it in y=mx+b form

y = -(4/5)*x-8
m x b
the m is your slope to get perpendicular you flip it and multiply by - so a slope perpendicular to it is 5/4

Answer 3

-1,3
so now you can plug in the coordinants to y=mx+b

3=5/4*(-1)+b sfb b=17/4

so y=5/4 *x +(17/4)

tto get it in the form the answer asks

y-5/4*x=17/4 subtract 5/4x
4*y-5*x=17 multiply by 4

Answer 4

rearrange the x and y terms your answer is

-5x + 4y = 17

Answer 5

:D Thank you so much! Dude you are awesome!

Answer 6

so long as you understand :)
