Question

Write the equation of the line in point-slope form. Show all work. (5 points)
(3, 5); slope = -9

This is my answer. I'm horrible at slope and if it's wrong I'm not intentionally getting it wrong. I'm just really bad at slope :/

y - 5 = -9(x - 3)
y = 27 + 9x + 5
y = 9x + 32

Answer 1

y-5=-9(x-3) <------------That IS point slope form
Point slope form of a line:
\[y-y1=m(x-x1)\]

Answer 2

In slope intercept form,
\[y=mx+b\]
y-5=-9x+27
y=-9x+32

You have a +9x in yours, not a -

Answer 3

Ohh ok, thank you!

Answer 4

Is it supposed to be y = 27 - 9x + 5 or do I have it right?

Answer 5

in slope intercept form, y=-9x+32

Answer 6

So wait it's supposed to be
y - 5 = -9(x - 3)
y = 27 - 9x + 5
y = 9x + 32
or
y - 5 = -9(x - 3)
y = - 9x + 32
y = 9x + 32

Answer 7

Why are you removing the - sign from in front of the 9?

Answer 8

It keeps removing it when I press post >:( It's there while I write it, then leaves when I press post.
I meant
y - 5 = -9(x - 3)
y = -9x + 32
y = -9x + 32

Answer 9

yeah that's right

Answer 10

Thank you!!
