Two Point Formula $$\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1}$$  worked examples Find the equation of the line passing through (2, -4) and (-3, 6).   $$\frac{y-(-4)}{x-2}=\frac{6-(-4)}{-3-2}$$  x1 = 2, y1 = -4, x2 = -3, y2 = 6 substitute into the formula $$\frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1}$$ $$\frac{y+4}{x-2}=\frac{10}{-5}$$ $$\frac{y+4}{x-2}=-2$$ simplify y + 4 = -2(x -2) multiply both sides by (x - [...]
