You have the following equation:
y = (3/2)x - 1
In order to graph the previous equation, you can cross a line troug the x and y intercepts.
the x intercept is:
y = 0 = (3/2)x - 1
(3/2)x = 1
x = 2/3
the y intercept is:
y = (3/2)(0) - 1
y = -1
Then, the points you can connet with a line are:
(2/3 , 0)
(0 , -1)
The graph is shown below:
