Question

Write an equation of the line that passes through (-1,3) and is parallel to the line y = 2x + 2.
y =

Answer 1

(Parallel lines have the same gradient)

y=2x+b

sub given point in

3=2(-1)+b

3=-2+b

Move -2 to the other side a a positive number

b=5

So the equation of the line is y=2x+5
