Question

Choose the equation of the line passing through the point (6, -2) and parallel to y = x + 7.

Answer 1

slope will remain 1
y - y1 = m (x - x1)

Answer 2

parallel means they have the same slope
so slope=1
y=mx+c
substitute the point (6,-2) im x and y
-2=(1)(6)+c
-2=6+c
-8=c
so the equation of the line is y=x-8

Answer 3

oh thank you so much. i understand how to do it now.
