Find the equation of a line that is parallel to y=2x+3 and passes through (-1,-1) a. y=2x+1 b. y=2x+3 c. y=4x+3 d. y=4x+5

parallel lines have the same slope

y = 2x+3

slope is 2

m=2 on the parallel line

point slope form of a line

y-y1 =m(x-x1)

y--1 = 2(x--1)

y+1 = 2(x+1)

distribute

y+1 = 2x+2

subtract 1 from each side

y = 2x+1

Choice A

the answer

b. they are parallel and will never intersect.
