use point-slope
OpenStudy (anonymous):
paralell linnes have same slope so resultant line will also have slope same as given line..
so that is m=slope=4
so now use this..
(y-y1)=m(x-x1)
plug in values ..
OpenStudy (help!!!!):
\[y-y _{1}=m(x-x _{1})\]
OpenStudy (help!!!!):
What I would first do is change the standard form to y-intercept. Then use point-slope form for the 2 coordinates.
OpenStudy (anonymous):
i did all that and got a answer that isnt one of the options

y = four thirdsx + 8
y = four thirdsx + 3
y = -three fourthsx + 8
y = -three fourthsx + 3

Graph it and translate the line
OpenStudy (help!!!!):
Its the first one
OpenStudy (anonymous):
-3y-4=4(x+3)
-3y-4=4x+12
-3y=4x+16
y=-4/3x+16/3
OpenStudy (help!!!!):
your slope you wrote down is incorrect, but rather 4/3

redo the standard form to y-intercept form
OpenStudy (anonymous):
y = 4/3x + 8
OpenStudy (help!!!!):
exactly the first choice
OpenStudy (anonymous):
Yep
OpenStudy (anonymous):
okay thanks
