Edit: I did this with the assumption that 12 was the diameter, if it's the radius disregard this please</h2>
Y=mx+b
m=slope
slopes of parallel lines are the same
y=3/4x+2
the slope is 3/4
the slope of a line parallel to that is 2/3
Y = (3/4)x - 3
Use two of the ordered points to find the slope.
Then use the slope and one of the ordered pairs to find the y-intercept.
Answer: 
Step-by-step explanation:
Given the following expression:

You need to substitute the given values of "a" and "b" into the expression. Notice that these values are:

Then;

Now you must solve the multiplications:

The final step is to add the numbers. Therefore, you get the following answer:

This means 11 + 1÷8
So 11 + 0.125
Final answer 11.125
Hope you understand :)
