1) y = 2x - 3
- Y-intercept: (0, -3)
- Slope: 2 (rise 2, run 1)
- Plot (0, -3), then go up 2 and right 1 to plot (1, -1). Draw line.
2) y = -3x + 2
- Y-intercept: (0, 2)
- Slope: -3 (rise -3, run 1)
- Plot (0, 2), then go down 3 and right 1 to plot (1, -1). Draw line.
3) y = (1/2)x - 5
- Y-intercept: (0, -5)
- Slope: 1/2 (rise 1, run 2)
- Plot (0, -5), then go up 1 and right 2 to plot (2, -4). Draw line.
4) y = -(2/3)x + 4
- Y-intercept: (0, 4)
- Slope: -2/3 (rise -2, run 3)
- Plot (0, 4), then go down 2 and right 3 to plot (3, 2). Draw line.
5) x + y = 4 → y = -x + 4
- Y-intercept: (0, 4)
- Slope: -1 (rise -1, run 1)
- Plot (0, 4), then go down 1 and right 1 to plot (1, 3). Draw line.
6) y = 3
- Horizontal line through y=3.
- Plot points (0, 3), (1, 3), (-1, 3), etc. Draw horizontal line.
