Question

4 && 5 struggling.... little difficult

Answer 1

I can’t answer 5 because I don’t know what was in Example two, but I can tell you how to graph the equation y = -200x + 2400!

This equation is in slope intercept form, which means that the number next to the variable is the rate of change and the number added onto the first term is the initial value. Since your initial value is 2400, your first point will be at (0, 2400). Each time x increases by 1, y will decrease by 200 (because the rate of change is -200). So your second point will be (1, 2200) and so on.
