The answer is A. y = -2/5
Answer:
The correct answer is B) d=250t.
Step-by-step explanation:
B is the correct answer because the total distance (d) equals 250 multiplied by the minutes (t) the runner has ran.
Answer:

And we can solve for
and we got:



And we can solve for
and we got:


So then the coordinates for B are (3,8)
Step-by-step explanation:
For this case we know that the midpoint for the segment AB is (2,5)
And we know that the coordinates of A are (1,2)
We know that for a given segment the formulas in order to find the midpoint are given by:

And we can solve for
and we got:



And we can solve for
and we got:


So then the coordinates for B are (3,8)
