Answer:
(2,-7)
Step-by-step explanation:
Use the midpoint formula! (Attached is a picture of it!)
1) Plug in the values:
(5-1)/2,(-6+-8)/2
2) Simplify:
4/2,-14/2
3) Solve:
(2,-7)
Answer:

Step-by-step explanation:
Given:
The two points on the line are:

Now, for a line with two points on it, the slope of the line is given as:

For the points
, slope is:

Now, for a line with slope 'm' and a point
on it is given as:

Plug in all the values and determine the equation of the line. This gives,

Therefore, the equation of the line is:

The expression given is

The sum of the expression will be,

The sum will be
The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
Answer:
Decreasing from x = 1 to x = 6.
