Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

Given the points (-8,4) and (-5,1), what is the slope?

Back

-1

Front

If a pizza costs $6.80 plus $0.90 for each topping, what is the total cost for a three-topping pizza?

Back

Total cost = 6.80 + (0.90 * 3) = $8.60
