Question

Look at the scatterplot below. It compares the number of hours students spentpreparing for a standardized test and their results on the exam. The line of fitfor the scatterplot is given by the equation y = 7x +45

Answer 1

Given data:

The given equation of the line is y=7x+45.

The y-intercept is the coordinate of y when x coordinate is zero.

`\begin{gathered} y=7(0)+45 \\ =45 \end{gathered}`

It means student score is 45 when study time is zero hours.

Thus, the option (B) is correct.
