Answer:
z / 7
Step-by-step explanation:
C = O / H
O = z
H = 7
Solution:
we are given that
If G is the midpoint of FH, it mean that
we are also given that
So we can write
So 
To find the average: the sum of the values/number of values
=250+310+275+195/4
=257.5
Let's start with y = 4x + b (since 4 is the slope);
We need to find what number should be put instead of b;
Then, let's see what needs to be done;
Plug in the y and x values from the coordinate (22,12) into y=4x+b;
12 = 4(22) + b
Solve;
12 = 88 + b
12 - 88 = b
b = -76
Remember the equation y = 4x + b? Put the -76 instead of b:
y = 4x + -76
or: y = 4x - 76
That is the equation.
To make it standard form, put x and y both in the left side, with x first then y:
-4x + y = -76
