The linear equation y=7x represents the cost y in dollars of x pounds of steak. Which ordered pair lies on the graph of the equation?

A; 2,14

B; 7,14

C; 7,7

D; 4,14

Y = 7x

ur answer choices are set up as (x, y) ... so it is just a matter of subbing

A. (2,14) ... x = 2 and y = 14

now sub it into the formula and see what you get ...

y = 7x

14 = 7 (2)

14 = 14 ... this is correct ... so this is the answer

B 7,14 is the answer
