Best ResponseYou've already chosen the best response.0Not quite. \[Slope =\frac{\text{Change in y}}{\text{Change in x}} = \frac{y_2y_1}{x_2x_1}\]

Best ResponseYou've already chosen the best response.0Once you have the slope, you can plug that into the point slope formula. \[yy_1 = M(xx_1)\] Where M is the slope.
