Which rule models the linear function in the table below? Pic below

I don't know the picture above. I can't see any but i can teach you how to solve it.So, if the graph is a straight line, it is the graph of a linear function. From a table, you can verify a linear function by examining the x and y values. The rate of change for y with respect to x remains constant for a linear function. This rate of change is called the slope.(hope you understood well)

i dont know the answer but here's a picture of a dog
