Yes. y = mx + b
perpendicular is y = -x/m + e
OpenStudy (anonymous):
Thanks I just don't get graphs....
OpenStudy (anonymous):
In time, with practice, you will.
OpenStudy (anonymous):
I have another question. Could you help me.

put these equations into this form and the answer becomes clear.
OpenStudy (anonymous):
A.
y = 3x – 4
B.
y = 3x + 4
C.
y = –3x + 4

Fine. You know how to find m and b
y = (slope) x + (y-intercept)
OpenStudy (anonymous):
I believe so.
OpenStudy (anonymous):
Compare y = -3x -4 with the options
OpenStudy (anonymous):
@ColePhelps1 What's the answer????
OpenStudy (anonymous):
I got it "y=-3x-4"
