Ineed answers ! i don't understand this at !

On function 1 - plot the points onto the graph and get your answer

On function 2 - use the answer to work in reverse to get your plot points and graph filled in

On function 3 - grab plotted points and put them in the graph

The first one you need to draw the line that the graph makes and at the bottom you put the slope and y-intersect. the 2nd one you use the parent function for X which is -2, -1, 0, 1, and you plug those numbers into the bottom equation to get your y's then graph the line. the 3rd one is the same to where you use the points that it gives you to determine the x and y values while figuring out the slope and y-intercept on the bottom.
