The equation is h(x) = theta0 + theta1 * x .

theta0 = 1, theta1 = 0.5 .

The graph is plotted between x and h(x) .

1) Consider x = 0. h(x) = 1 + 0.5 * 0 = 1 . There fore for x = 0 , h(x) = 1.

2) Consider x = 1. h(x) = 1 + 0.5 * 1 = 1.5 . Therefore for x = 1, h(x) = 1.5 .

3) Consider x = 2. h(x) = 1 + 0.5 * 2 = 2 . Therefore for x = 2, h(x) = 2 .

If you join these points (0,1) , (1,1.5) and (2,2) you will get a straight line as shown in third graph.

Theta1 decides the slope of the graph (i.e inclination of the graph)
