Question 1058949: Line QR goes through points Q(0, 1) and R(2, 7). Which equation represents line QR?
y – 1 = 6x
y – 1 = 3x
y – 7 = 2x – 6
y – 7 = x – 2 Answer by math_helper(2461) (Show Source):

One way to write the equation of a straight line is slope-intercept form:
where:
m = slope
b = y-intercept (the point Q tells us b=1 because at x=0, y=1)
Slope, m, is found by "rise over run" or "change in y over change in x":
m = (7-1)/(2-0) = 3
So it should be clear now which answer is correct.
