If you're talking about #5, where you have to graph the equation . . .
All you have to do is find two points on the graph, and draw a line between them.
How do you find points ? That's where you are in control !
Just pick any number you like for 'x', and then use the equation
to calculate the 'y' that goes with it.
Examples:
Pick 'zero' for 'x'.
Y = (1/2)x + 3
Y = 3
Pick 10 for 'x'.
y = (1/2)x + 3
y = 5 + 3
y = 8
Just create two points that way, using the equation. Then mark
the two points on the graph, and draw a line through the two points.
