Step-by-step explanation:
In order to graph the line, you should get the points where the line crosses the axis:
y = 5 - 1.5*x
0 = 5 - 1.5*x
-5 = -1.5*x
-5/(-1.5) = x
3.33 = x
So (3.33;0) is where the line crosses the X axis.
y = 5 - 1.5*x
y = 5 - 1.5*0
y = 5
Si (0;5) is where the line crosses the Y axis.
