Solution to question 1 a. L1 is the line y =1 as the y coordinate is always 1 regardless of the x coordinate. For L2 if we construct a small table of convenient points, we have x 0 1 2 y 0 2 4 We can observe that we have the line y =2x. For L3 we see that when y =0 we have x =5 the line crosses the x-axis at (5, 0). When x =0 we have y =5, the line crosses the y-axis at (0,
