Answer:
Step-by-step explanation:
The coordinates of the midpoint M are the average of the coordinates of the two endpoints:

Plug the known coordinates of the midpoint:

Solve for x and y:


Slope formula: m =
(Knowing that m represents the slope)
Substitute (1,0) for (x1,y1), and (-1,-3) for (x2,y2)
Slope of the line of (1,0) and (-1,-3) is:
m =
=
=
(Simplify)
Slope of the line of (1,0) and (-1,-3) is

let's plug in the value of y :
Answer:
-7.65
