that the slope between any two specific coordinate points (x₁, f(x₁)) and (x₁+ Δx, f(x₁+ Δx)) is equal to the y-value of the second minus the y-value of the first, divided by the x-value of the second minus the x-value of the first. And like before, we can still use this slope to write the equation
