Question 298515
y = 1/2x - 3/2 

To graph you need at least two coordinates...

So:  

Start with x = 0
y = 1/2(0) - 3/2
y = -3/2
first coordinate (0,-3/2)

Now do y = 0
0 = 1/2x - 3/2  add 3/2 to both sides
3/2 = 1/2x  multiple both sides by 2
6/2 = x
3 = x
second coordinate (3,0)

Graph these two point and draw a line connecting them

you have now graphed the equation
