Answer:
The given function is:
[tex]f(x)=\frac{x}{2}-2[/tex]
Replacing , f(x) by , y in the above equation
[tex]y=\frac{x}{2}-2\\\\y=\frac{x-4}{2}\\\\2 y=x-4\\\\x-2 y=4\\\\\frac{x}{4}-\frac{2y}{4}=1\\\\ \frac{x}{4}+\frac{y}{-2}=1[/tex]
The given equation of line has , x intercept , (4,0) and y intercept (0,-2).To get a unique line we need two distinct points.So, join the two points ,(4,0) and (0,-2).
