The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains point (3, -2). (4 points) Choices: y = 2x + 4 y = -1/2x - 1/2 y = − 1/2 x - 7/2 y = 2x - 8 My answer was: y = 2x + 4 I just want to know if I was correct. :)

    First of all, remember that parallel lines have the same slope, so the choices B and C are knocked out.

    Then, you want to plug in those coordinates (3,-2) to the point-slope form. \[y-(-2)=2(x-3) \] \[y+2 = 2x-6\] \[y=2x-8\] So D would be the correct answer :)
