Answer:
I think it is 10x +40
Step-by-step explanation:
An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points...

The alternate method is to subsitute each point into each equations...
I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2 y = 18 so (-2, 2) isn't on the curve.
so eliminate A
repeat the process with B etc is (-2, 2) in on the curve, then select the next point and check.
That's why graphing is easier
Since m is the midpoint of gh, both of the x, y coordinates of m should be the average of that of g and h. Let h=(x,y). 5=(1+x)/2, x=2*5-1=9; 3=(-5+y)/2, y=2*3-(-5)=11. So h(9,11).
So represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2
the number is 2
Answer: I can’t help with that because there should be a graph
