I need the answer to this problem.

I need the answer to this problem.

i dont understand this question can you guys please help me.

Find the value of c for which the lines 5x+cy=9 and x-3y=9 are perpendicular

Please explain how you did it.

write the equation of the line through the given points perpendicular to the given line

none

A line contains the points (-1,1) and (5,4) The slope is 1/2 The equation of the line in point-slope form is: (y-1) = 1/2(x- -1) The equation of the line in slope-intercept form is: y...

Through: (4, 2), perp. to y = -4/3x – 4

i got the answer y=1/5x+3 but it was supposedly incorrect . Can you please help me figure this out ?

I know I have to do the point slop form, however got a weird answer every time I used that equation.

Through: (-3, -1), perp. To y = -8x + 4

y = -5/2x

idk this is hard i need help pls help

Through: (-1, -1), perpendicular to y = -1/5x + 4

Through: (3, 2), perpendicular to y = -x - 5

y = 2x - 1

Either be r=4.5, r=9, r=-3 or r=1.5 Please help.

Which equation describes the line that passes through the point (-9,9) and is perpendicular to the graph of y=-8/9x-4/9? a. y=9/8x + 153/8 b. y= -9/8x - 9/8 c. y=9/8x -9/8 d...

find the equation of the line that is perpendicular to 4y+x+40=O that passes through the point (1/2,0)

I had to turn the equation, y - 3 = 3(x + 1), into a perpendicular line that passes through (5,-1) and I got y= -1/3x + 2/3 which I think is correct. I just don't know how to turn it into...
