use the graph below to answer the following question: if slope is calculated using the equation, "m = (y2-y1) / (x2-x1)," what is the slope of the secant line? be sure to include all math work and units in your final answer.

8 cm/s

Explanation:

When the time is 0 s (x₁ = 0 s), the position of the rolling ball is 0 cm (y₁ = 0 cm).

When the time is 6 s (x₂ = 6 s), the position of the rolling ball is 45 cm (y₂ = 45 cm).

Using these 2 points, we can find the slope (m) of the secant line.

m = (y₂ - y₁)/(x₂ - x₁) = (45 cm - 0 cm)/(6 s - 0 s) = 8 cm/s (we round off to 1 significant figure)

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.
