Write the equation of the line that is parallel to the line y = -3x + 12 and passes through the point (-1, 6).
y = one thirdx + 7
y = -3x + 3
y = one thirdx + 3
y = -3x + 7

@misty1212 srry for all these questions i had 32 and i needed help w. eight of them and my mom did not understand it so
OpenStudy (misty1212):
HI again!!
OpenStudy (misty1212):
what is hte slope of \(y=-3x+12\) ?
OpenStudy (anonymous):
umm -3
OpenStudy (misty1212):
yes
and so will any parallel line have slope \(-3\)

so either B or D
how will you choose?
OpenStudy (anonymous):
how will i
OpenStudy (anonymous):
slope intercept form again
OpenStudy (misty1212):
you can plug in the numbers and see which one works
OpenStudy (misty1212):
or you can write
\[y-6=-3(x+1)\]and find \(y\)

ok
OpenStudy (anonymous):
y-6+6 = -3x -3+6
OpenStudy (anonymous):
sorry did not go step by step kind of rushed through
OpenStudy (misty1212):
ok that works
OpenStudy (misty1212):
you get
\[y=-3x+3\] and that should be correct
