Choose the slope-intercept equation of the line that passes through the point (-2, 4) and is parallel to y = -3x + 6.
y = one thirdx + 14 thirds
y = 3x + 10
y = -3x - 2
y = -one thirdx + 10 thirds

Please help. :|
OpenStudy (stefrheart):
okay so first you need to put into point slope form
OpenStudy (anonymous):
Okay. Is that something like y2-y1/x2-x1? I forget. :|
OpenStudy (stefrheart):
no its the y-4=-3(x+2)
OpenStudy (anonymous):
Okay.

OpenStudy (stefrheart):
so then you need to distribute the -3
OpenStudy (anonymous):
Okay, so i distribute them through (x+2)?
OpenStudy (stefrheart):
yes
OpenStudy (anonymous):
I got -3x+1
OpenStudy (anonymous):
Well Y-4=-3x+1

OpenStudy (stefrheart):
okay so now you add the 4 on both sides
OpenStudy (anonymous):
Right, Thats because its passing through the equal sign, Correct?
OpenStudy (stefrheart):
well thats how you isolate the y
OpenStudy (anonymous):
Alright, So i ended up with Y=1x+1
OpenStudy (stefrheart):
wait you should have y=-3x+5

Okay, That was my mistake on the math, Your right
OpenStudy (stefrheart):
oh wait hold on let me write it out i may be wrong
OpenStudy (anonymous):
Okay. I got it because i added 4 to -3
OpenStudy (stefrheart):
im sorry its y=-3x-2
OpenStudy (anonymous):
Okay Now what
