Question

What does slope mean in context?Answer Choices: A. For every 1% increase in 4th grade pass rate, the predicted 8th grade pass rate will increase by 25.6%B. For every 1% increase in 8th grade pass rate, the predicted 4th grade pass rate will increase by 1.1%C. For every 1% increase in 4th grade pass rate, the predicted 8th grade pass rate will increase by 1.1%D. For every 1% increase in 8th grade pass rate, the predicted 4th grade pass rate will increase by 25.6%

Answer 1

Answer: The mathematical meaning of the slope in the following context is as described below:

(A):

$\begin{gathered} S=\frac{\text{ 8th grade pass rate}}{\text{ 4th grade pass rate}} \\ \\ S=\frac{25.6\%}{1\%} \\ \end{gathered}$

(B):

$\begin{gathered} S=\frac{\text{ 4th grade pass rate}}{\text{ 8th grade pass rate}} \\ \\ S=\frac{1.1\%}{1\%} \end{gathered}$

(C):

$\begin{gathered} S=\frac{\text{ 8th grade pass rate}}{\text{ 4th grade pass rate}} \\ \\ S=\frac{1.1\%}{1\%} \end{gathered}$

(D): Finally the answer for the last part is:

$\begin{gathered} S=\frac{\text{ 4th grade pass rate}}{\text{ 8th grade pass rate}} \\ \\ S=\frac{25.6\%}{1\%} \end{gathered}$
