Which equation represents a line which is parallel to the line y=-3x-7?
given line has a slope -3
find the line with same slope
a.
x-3y=-24=>x%2B24=3y=>%281%2F3%29x%2B8=y=> slope is 1%2F3-> not same
b.
+x%2B3y=18=>+3y=-x%2B18=>+y=-%281%2F3%29x%2B6-> not same
c.
y-3x=3=>y=3x%2B3-> not same

d.
3x%2By=-6=>y=-3x%E2%88%926-> same slope=>this line is parallel to the line y=-3x-7

answer:
d. 3x%2By=-6
