Question

write and equations of the line that passes through the given point and is parallel to the given line.
4.(6,8) y=-5/2x+10

Answer 1

8=-5/2*6+b
+15
23=b
y=-5/2x+23

Answer 2

okay thanks what about (-1,2), y=5x+4

Answer 3

Well, you would plug in what you know. -1 is x and 2 is y. You would leave b alone. If you want the same slope, then the m stays the same so:
2=5(-1)+b
+5
7=b
y=5x+7

Answer 4

wait in the first one how did you go from 23=6+b to 23=b?
