Question: Which of the following sketches could represent
y = 2x - 3 ?
1. **State the problem:** We need to determine which graph correctly represents the equation $$y = 2x - 3$$.
2. **Recall the form and properties:** The equation is in slope-intercept form $$y = mx + b$$, where $$m$$ is the slope and $$b$$ is the y-intercept.
3. **Identify slope and intercept:** Here, $$m = 2$$ (positive slope) and $$b = -3$$ (y-intercept below zero).
4. **Interpret the slope:** A positive slope means the line rises from left to right.
5. **Interpret the y-intercept:** The line crosses the y-axis at $$-3$$, which is below zero.
6. **Find the x-intercept:** Set $$y=0$$ to find x-intercept:
$$0 = 2x - 3$$
$$2x = 3$$
$$x = \frac{3}{2} = 1.5$$
The x-intercept is positive, so the line crosses the x-axis to the right of the y-axis.
7. **Match with options:**
- Positive slope: options A and B
- Y-intercept below zero: option B
- X-intercept to the right of y-axis: option B
8. **Conclusion:** The correct graph is option B.
**Final answer:** Option B represents $$y = 2x - 3$$.
