Algebra-1

To determine which ordered pair is on the line represented by y=2x, where y represents the total cost in dollars and x represents the number of fruits Doris buys, we need to substitute each option into the equation and check.

Given equation: y=2x

Let's check each option:

A. For (8,15): y=2 ⋅ 8=16

This does not match 15, so (8,15) is not on the line y=2x.
