Slope-Intercept Form of a Linear Equation How To Get To Slope-Intercept Form Notes: Given Two Points x y X1 Y1 X2 Y2 Step 1) Make a table Use the two points to calculate SLOPE (m) Y2 – Y1 m = X2 – X1 Step 2) Plug m and one point into y = mx + b Solve for b (Y1) = m(X1) + b Step 3) Write general formula with m and b y = mx + b m = slope b = y-intercept Slope-Intercept Form of a Linear Equation
