"Determine the point of intersection of each pair of equations by plotting accurate graphs."

This question asks to 'determine' the point of intersection by plotting accurate graphs. I'm not sure how one is supposed to be able to 'determine' the point of intersections just by plotting the equations on graphs without simultaneously solving them for x and y... Quite confused...

If you've been asked to determine the intersection by 'plotting accurate graphs', then it seems like you're expected to plot the given equations on graph paper, and then check the x and y co-ordinates of the point of intersection on your graph, rather than solving the equations directly.
