Solve the Problem Using Your Calculator A) Y=-194-0

question 2

Short Answer

Solve the problem using your calculator.
-Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both tests and the results are shown below. Use a graphing calculator to model the data with a linear function that predicts a student's score on Test B as a function of his or her score on Test A.
$\begin{array} { c | c | c | c | c | c | c | c | c | c } \text { Test A } & 48 & 52 & 58 & 44 & 43 & 43 & 40 & 51 & 59 \\\hline \text { Test B } & 73 & 67 & 73 & 59 & 58 & 56 & 58 & 64 & 74\end{array}$
A) y=-19.4-0.930x
B) y=19.4+0.930x
C) y=-0.930+19.4x
D) y=0.930-19.4x

• A) y=-19.4-0.930x
