Best ResponseYou've already chosen the best response.2Part 2) You have a point (6, 3) and you have the slope (2). PointSlope formula: y  y1 = m(x  x1) y  3 = 2(x  6)

Best ResponseYou've already chosen the best response.2Change from PointSlope to Slopeintercept. y = mx + b Remember m is slope and b is yintercept. y  3 = 2(x  6) y = 2x  9 Part 3) Parallel lines have the same slope but different yintercepts. So you keep the y = 2x part and add whatever number you want.

Best ResponseYou've already chosen the best response.2Part 4) Perpendicular lines' slope is the opposite reciprocal. So instead of 2, you're slope would be 1/2. This time the equation would be y = 1/2x
