Answer:
Table D
Step-by-step explanation:
Linear equations have a proportional relationship between x & y values. This means that for every time x goes up, y goes up a certain amount.
For Table D, every time x goes up 1, y goes up 2. We can see this by subtracting one of the smaller y values from one of the larger y values.
9-7=2
7-5=2
5-3=2
All of them are equal to 2, so we know that y increases at a constant rate, thus making it a linear equation.
