Question 1004020: A line M is passing through the points (2, 5) and (-2, 1). Another line L is parallel to the line M and passing through the point (1, 7). Find the following:
(A) The slope of M
(B) The slope of L
(C) The equation of L in the form y=mx+b

You can put this solution on YOUR website!
slope of M is change in y/change in x
=-4/-4=1
Slope of L is the same, 1, since it is parallel.
point slope formula for L
y-y1=1(x-x1)
y-7=1(x-1)
y-7=x-1
y=x+6
