Trey believes there is a correlation between the number of texts sent during class and GPA. He collected data and found that the

vichka [17]

Answer: First Option

The slope is −0.4. Starting at 3.8, the GPA will decrease by 0.4 for every text sent in class.

Step-by-step explanation:

The equation of a line has the following form

$y=mx+b$

Where m is the slope of the line and b is the intercept with the axis of the y

In this case, the equation is:

$y = 3.8 - 0.4x\\\\y=-0.4x+3.8$

Observe that

$m = -0.4\\b = 3.8$

So if x represents the number of texts sent during classes, this means that $x\geq 0$

When x increases by one unit then y decreases -0.4. For example when $x=1$ then $y=3.8-0.4=3.4$

Then the greatest value it can take the GPA is 3.8. Therefore we can say that the function starts at y = 3.8.

The answer is the first option
