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

Solve for the equation of the line by the equation,
                      y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)
Substituting the values of abscissas and ordinates from the points given,
                     y - 1 = ((7 - 1) / (2 - 0))(x - 0)
Simplifying the equation, 
                        y - 1 = 3x
The final equation is the second choice, y - 1 = 3x.
