Question

a. find the slope of the secant line from $x_1 = 0$ to $x_2 = 4$.
the slope of the secant line is 150.
(round to the nearest whole number as needed.)
b. the actual average yearly increase from 1994 to 1998 was 141. does the slope from part (a) underestimate or overestimate this value? by how much?
the slope from part (a) overestimates the actual average yearly increase.
the slope from part (a) differs from the actual average yearly increase by $\square$.

Explanation:

Step1: Identify the values

We have the slope from part (a) as \(m_1 = 150\) and the actual average yearly increase \(m_2=141\).

Step2: Calculate the difference

The difference \(\Delta m=m_1 - m_2\). Substitute \(m_1 = 150\) and \(m_2 = 141\) into the formula: \(\Delta m=150 - 141\).
