1. A.3(B) Amanda is trying to figure out how much picture frames cost at Hobby Lobby. She knows that the points (4, 29) and (8, 58) represent the number of frames x and the cost y of the frames. What is the rate of change that shows cost per frame? What is the key word in this problem? What is the formula for slope? (Check your formula chart) Step 1: Label points (x₁, y₁) & (x₂.Y2) Step 2: Substitute values into slope formula Step 3: Simplify your fraction What does it represent? m=
