Question

what is -x+y=5 in y=mx+b form?

Answer 1

just add the x to both sides

y=x+5

Answer 2

do you know how that equation will be if it was perpendicular?

Answer 3

Perpendicular to what?

Answer 4

perpendicular to a line that has an equation of -x+y=5

Answer 5

and passes through points (2,-5)

Answer 6

You want the equation of a line that is perpendicular to -x+y=5 and that passes through the point (2,-5)?

Answer 7

yes please

Answer 8

Well since we put -x+y=5 into y=mx+b form y=x+5 we can see the slope is 1. a line perpendicular to that would have a slope of -1. So use that and your point to find the equation.

y+5=-1(x-2)

simplify that

Answer 9

would it be the same if it were solving for a parallel line?

Answer 10

No, parallel lines have the same slope.

Answer 11

thank you :)

Answer 12

You're welcome

Answer 13

solve for y
