WEBStep 1: Identify the values of x 1 , x 2 , y 1 , and y 2 . x 1 = 2. y 1 = 1. x 2 = 4. y 2 = 7. Explain. ( 2, 1) ( 4, 7) ( x 1, y 1) ( x 2, y 2) x 1 x 1 st. y 1 y 1 st. x 2 x 2 nd. y 2 y 2 nd. Step 2: Plug in these values to the slope formula to find the slope. Slope = y 2 − y 1 x 2 − x 1 = 7 − 1 4 − 2 = 6 2 = 3. Step 3: Gut check.
