Question

Annie was given two pieces of information and must write the equation of a line. She knows the line crosses the y-axis at the point(0,6)and has a slope of7. What is the equation of the line?

A.y=7x+6
B.y=7x−6
C.y=6x+7
D.y=−6x+7

Answer 1

y-y1 = m(x -x1)
y - 6 = 7(x-0)
y - 6 = 7x
y = 7x +6

The answer is A
