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

line of best fit for his data can be modeled by the equation y = 3.8 − 0.4x.
Identify and interpret the slope in this scenario.

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

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

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

I need help in "Matlab' with how to "Create a column vector from 15 to -25 with a step size of 5"
Alekssandra [29.7K]

Answer:

x=[15:-5:-25]'

Step-by-step explanation:

In order to create a vector you need to use this command:

x = [j:i:k]'

This creates a regularly-spaced vector x using i as the increment between elements. j is the initial value and k is the final value. Besides you need to add the character ' at the end in order to convert the arrow vector in a column vector
