Write the equation of the line that is perpendicular to 4x+3y=18 and passes through the point (8,-2)?

Answer 1

4x+3y=18

3y=-4x +18

Y= -4x/3 +18

M= 3/4 opposite inverse of -4/3 because is perpendicular.

( 8,-2)

Y=mx+b

-2=3/4*(8)+ b

-2= 6+b

b= -6-2

b= -8 therefore the equation is

y= 3x/4-8 buhala!! :)

Simple get the slope from first equation after plug values into slope intercept form to find b after you get b then you have all the values of the equation. :)

Answer 2

The equation will be in the form 3x-4y = c. Just interchange the numbers that x and y are being multiplied by and ALSO change one the signs.

Now find c using the point (8,-2) in the equation 3x-4y=c
