Answer:
Step-by-step explanation:
Use the midpoint formula to solve:
We know the midpoint and one set of coordinates, so filling those in:
Since the -7 is the x coordinate of the midpoint, we set the x part of the equation equal to -7 and solve for x, and then do the same for y. The 2 equations are:
and 
We solve each one of these to get the x and y coordinates of the other endpoint. In both cases, multiply both sides of the equations by 2 and then solve by either adding or subtracting.
-14 = x - 19 so
5 = x
16 = y + 30 so
-14 = y
The coordinates of the other endpoint are (5, -14)
The answer is 64 with a remainder of 5

Answer:
y=0.5x+8
Step-by-step explanation:
Use the formula for the equation of a line y=mx+c where m is the slope and c is a number.
To find the slope, take two points (x₁,y₁) (x₂,y₂) and put them into the slope equation m=(y₂-y₁)/(x₂-x₁):
We can take two points from the graph: (2,9) (4,10)
m=(y₂-y₁)/(x₂-x₁)
m=(10-9)/(4-2)
m=1/2 or 0.5
Now sub this value in for m and our formula looks like this:
y=0.5x+c
To find the value of c, sub in one of the points, eg. (4,10)
y=0.5x+c
10=0.5(4)+c
10=2+c
c=8
So now that we now m and c, our equation is complete :D
y=0.5x+8
346 divided by 2 would be 153. Subtract 92, and that would lead you with 61.
Therefore, the ultimate answer is 61.
