Anyone willing to help me?
Write the equation of the line that is parallel to the line 4x - 3y = -12 and passes through the point (-3, 4).
A. y = four thirdsx + 8
B. y = four thirdsx + 3
C. y = -three fourthsx + 8
D. y = -three fourthsx + 3

you should know that if two lines are parallel, that means they have the same slope.
so lets find the slope of 4x-3y=-12
do you know how?
OpenStudy (jocelynstalnaker):
Yes, well tell me if i'm right.
3y=-12+4x

Then divide 3
OpenStudy (jocelynstalnaker):
y=-4+
OpenStudy (jocelynstalnaker):
y=-4+4/3x?
OpenStudy (nikato):
it shouldve been 3y=12+4x not negative 12
but it wouldnt really affect you answer in this question
OpenStudy (jocelynstalnaker):
Oh ok. so y=4+4/3x

OpenStudy (nikato):
so your equation would be y=4+ 4/3x
so whats the slope?
OpenStudy (jocelynstalnaker):
4/3? or 4?
OpenStudy (jocelynstalnaker):
4/3 right?
OpenStudy (nikato):
yea, 4/3 is right
remember slope-intercept form which is what you put it in
