Answer 1

To determine which graph is correct, you want to determine the x and y intercepts. By plugging in y=0, you will get the x-intercept. By plugging in x=0, you will get the y-intercept. It is found that these values are (-6,0) and (0,-2). Therefore, we can see in the options that Graph 2 is the only one with these points.
