x = 2 , 4 , 6 , 8
y = 18, 34, 50, 66
This is supposed to be a table where the x lines up with the y in order
How would I find the equation to solve this when x = 20?
x goes up by +2
y goes up by +16 but starts with 18
I already posted this and got the answer: y = 2 + 8 x
But I want to know, how you come up with the equation?
Where did the 8 and 2 come from?
