Question

What is the equation of a line that is parallel to y = 6x + 7 and passes through (0, 9)? Enter your equation in the box.

Answer 1

y = 6x + 9

Explanation:

parallel lines have equal gradients.

y - y1 = m(x -x1)

since the lines are parallel your m = 6.

y - y1 = 6(x - x1)

(x1 ; y1) is given (0 ; 9)

y - 9 = 6 (x -0)

y = 6x + 9
