x: 7, 4, 10

y: 4

Step-by-step explanation:

y = x - 3

Plug one value of x (given in the chart) to identify the value of y

One x value can be 7 (as it is shown)

so plug in 7 for x in the rule: y = x - 3

y = 7 - 3

Solve for y if y = 7 - 3

y = 4

so when x = 7, y = 4

(Keep doing this format to get every x or y value)
