Question

Write the equation of a line that passes through the point (1,-3) and is parallel to the line 7x + y = -5.

Answer 1

y=-7x-5

m=-7

(y-y1)=m(x-x1)
(y+3)=_7(x-1)

Answer 2

(y+3)=-7(x-1)
then you will get

y=-7x+4

Answer 3

Since it's parallel to the line, they'll have the same slope
plug in the numbers you know & solve for B
