# How do you find the domain and range for y=-1/2x+3?

Domain: $\left(- \infty , + \infty\right)$
Range: $\left(- \infty , + \infty\right)$

#### Explanation:

For any linear function of the form $y = m x + b$ the domain and range is the set of all real numbers because, a line extends infinitely in both directions.

Kindly see the graph of $y = - \frac{1}{2} x + 3$.

graph{y=-1/2x+3[-20,20,-10,10]}

God bless....I hope the explanation is useful.
