put in two points
my math teacher formulas: slope: m = Δx / Δy Δx and Δy are just the x and y positions subtracted from the other, the order doesn't matter in context of finding the slope. y-intercept: b = y - mx b is the y-intercept. x-intercept: 0 - b / m or -b / m x: x = y - b / m also the inverse function of a linear equation. y: y = mx + b (this one is the formula for a linear equation, which is solving for y)
