Question

(3,-3),y=x+5 Write an equation of the line that passes through the given point and is perpendicular to the given line.

Answer 1

x=y

Answer 2

dont you have to make the given slope opposite

Answer 3

sorry x=-y

Answer 4

sritama idont think thats right

Answer 5

why not -x

Answer 6

perpendicular means if the first line's gradient is n, the other line's gradient is -1/n
so the line you are looking for has the gradient of -1/1 which is just -1
(y-(-3))/(x-3)=-1
y+3=-x+3
y=-x+6

Answer 7

oops
y+3=-x+3
y=-x

silly mistake, sorry

Answer 8

hmmmm

Answer 9

Draw the picture. It all becomes clear.
