Answer 1

From the graph, we can see that the two lines intersect at the point (1,3). So, we need to find the set of equations, from the options given, that will intersect at this point. To do this, we replace the inequality signs with '=' signs and solve for x and y as a set of simultaneous equations.

Hopefully it will only be one of the four options that works out as x =1, y = 3 and this will be the correct answer!
