Y = 2x + 50,
It's easier to look at the first set of numbers and then make a formula from there. so we need x to be zero and y to be 50, which is why the formula listed works.
I can not see the answer or the question
A common denominatortor 9 and 12 is 3 and 6
B is as it is a logical form of reasoning. if a=50, b=30, c=20
if a > b and b > c then a > c
