Step 1:
Write the function.
[tex]\begin{gathered} y\text{ = 3 - }\frac{1}{2}x \\ \end{gathered}[/tex]Step 2:
Rearrange the function in the form of y = mx + c
[tex]\begin{gathered} y\text{ = -}\frac{1}{2}x\text{ + 3} \\ \text{The graph will come downward from left to the right because of it } \\ \text{negative slope.} \\ \text{When x = 0, } \\ y\text{ = -}\frac{1}{2}(0)\text{ + 3 = 3} \\ \text{when y = 0} \\ 0\text{ = -}\frac{1}{2}x\text{ + 3} \\ \frac{1}{2}x\text{ = 3} \\ x\text{ = 6} \end{gathered}[/tex]Step 3:
You can plot the graph using the coordinates (0, 3) and (6, 0)
