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

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:

Observe that

So if x represents the number of texts sent during classes, this means that 
When x increases by one unit then y decreases -0.4. For example when
then 
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 don't get your question
I think the distance is 3/7. This is because 4 minus 1 is 3 (they are both in the same quadrant, so u subtract/are both positive too). -3 is three away from zero and 4 is 4 away from zero. If you add those together, you get those points (also, u add numbers in different quadrants together). Therefore, the distance is 3/7. Hope this helps!
