Solutions
1. (0, -3)
The y-intercept is the constant term b in y = mx + b, so the line crosses the y-axis at (0, -3).
2. (0, 1)
The y-intercept is the constant term b in y = mx + b, so the line crosses the y-axis at (0, 1).
3. (0, 1)
The y-intercept is the constant term b in y = mx + b, so the line crosses the y-axis at (0, 1).
4. (0, 4)
The y-intercept is the constant term b in y = mx + b, so the line crosses the y-axis at (0, 4).
