In the table, (x) shows the number of tomatoes and (y) shows the cost. Based on the table, you can write the equation (y) equals some number times (x). what is the number?
x = 2 3 4 5
---------------------------------
y = 0.9 1.35 1.8 2.25
The equation is .45x=y. 0 1 2 3 4. 5 0 .45 .9 1.35. 1.8 2.25 The reason is because the y value increases by .45 ,but there is no value in the y value when x equals 0. So it will all conclude to .45x=y.
