Hi i really need some help

Two points I see on here are (0,0) and (5,300) so to get from 0 to 5 you go up by 5 and then to get from 0 to 300 you go up by 300. And then do change in y over change in x. So the change in y is how many you went up by on the y coordinate. So it’s from 0 to 300 so it’s 300. And then change in x is how much you went by in the x-coordinate so here it’s going to be up by 5 on the x coordinate. So now take the change in y which is 300 and divide by change in x which is 5 and 300/5 is 60 so the rate of change is 60. Hope this helps

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
