Answer:


y=224-16x

Explanation:

Stare at the table for a bit. if you look at the y you can tell that the difference between two rows is the same, and it's equal to 32: every time x increases by 2, y decreases by 32; it means that if x increased by 1, y would decrease by 16. At this point we can write the equation as
y=q-16x To find q there are 2 ways: one is to plug the value from any line in place of y and x, or, more elegant, is to backtrack the table: if y goes down by 32 when x raises by 2, it emans that if x decreases by 2, y will go up by 32. And 192+32 is 224, our q value.
