Question

slope-intercept equation of the line that passes through the point (-5, -1) and is perpendicular to y = x + 2.

Answer 1

A clue: if it is perpendicular it is going to be of the form y = -x + c

Can you finish it with what you have?

Answer 2

yes most likely.. thank you dmot7291

Answer 3

What i would do is find the line itself by using the point-slope formula. That is: (y-b)=m(x-a) where a is -5 and b is-1 and m is -1 since you are looking for the perpendicular line. Then you would solve for the variable y to get y=-x+5-1 which simplifies to y=-x+4. Make sense?

Answer 4

It makes sense, but I think you have gone wrong with a minus sign somewhere!

y-b = m(x-a)

y -(-1) = -1(x - (-5))

y +1 = - (x +5)

y +1 = -x-5

y = -x -6

Answer 5

hmm probably but the fact that you were able to point that out means you know what you're doing now so good job!!

Answer 6

:) Just be careful with those minus signs, it is how they try to trick you!
