Question

How do I graph Y=1/2x - 3

Answer 1

Assuming you mean y = (1/2)x − 3, do this:

1. Identify slope and y-intercept:
- Slope m = 1/2
- y-intercept b = −3 (point (0, −3))

2. Plot the y-intercept: put a point at (0, −3).

3. Use the slope to get another point: slope 1/2 means “rise 1, run 2.”
- From (0, −3) go right 2 and up 1 → point (2, −2).
- Or go right 6 and up 3 → point (6, 0) (the x-intercept).

4. Draw a straight line through those points — that’s the graph.

Extra sample points: x = 4 → y = −1; x = −2 → y = −4. Domain and range: all real numbers.

If you want, I can draw a quick sketch or give the points in table form.
