1) y = 2x - 3
- Plot the y-intercept (0, -3).
- Use the slope 2 (rise 2, run 1) to find another point: from (0, -3), move up 2 and right 1 to (1, -1).
- Draw a line through these points.
2) y = -3x + 2
- Plot the y-intercept (0, 2).
- Use the slope -3 (rise -3, run 1) to find another point: from (0, 2), move down 3 and right 1 to (1, -1).
- Draw a line through these points.
3) y = (1/2)x - 5
- Plot the y-intercept (0, -5).
- Use the slope 1/2 (rise 1, run 2) to find another point: from (0, -5), move up 1 and right 2 to (2, -4).
- Draw a line through these points.
4) y = -(2/3)x + 4
- Plot the y-intercept (0, 4).
- Use the slope -2/3 (rise -2, run 3) to find another point: from (0, 4), move down 2 and right 3 to (3, 2).
- Draw a line through these points.
5) x + y = 4
- Rewrite as y = -x + 4.
- Plot the y-intercept (0, 4).
- Use the slope -1 (rise -1, run 1) to find another point: from (0, 4), move down 1 and right 1 to (1, 3).
- Draw a line through these points.
6) y = 3
- This is a horizontal line.
- Plot any two points with y-coordinate 3, such as (0, 3) and (2, 3).
- Draw a horizontal line through these points.
