A1.C.1Slope & slope-intercept01/05

Slope and slope-intercept form.

Find the line through these two points

(x_{1}, y_{1}) = (1, 2) and (x_{2}, y_{2}) = (4, 11)

Step01of 05

Slope m measures steepness — how much y changes per unit of x. The formula:

m = \frac{y _{2} - y _{1}}{x _{2} - x _{1}} = \frac{Δ y}{Δ x}

"Rise over run." Pick the points in any order — just be consistent on top and bottom.
