Question

The graph below shows four straight lines, W, X, Y, and Z.

Answer 1

The answer is X- the gradient is +5, and the line goes through +5 on the graph

Answer 2

The y intercept (when x = 0) is at y=5 as y=3(0) + 5 allows y to equal 5. Therefore the answer is line x as it also goes through 5 when x = 0
