Question: Which of the following graphs represents the equation $2x - 2y = 36$?
1. **State the problem:** We need to identify which graph corresponds to the equation $$2x - 2y = 36$$.
2. **Rewrite the equation in slope-intercept form:**
$$2x - 2y = 36$$
Subtract $2x$ from both sides:
$$-2y = -2x + 36$$
Divide both sides by $-2$:
$$y = \cancel{-2} \frac{-2x}{\cancel{-2}} + \cancel{-2} \frac{36}{\cancel{-2}}$$
Simplify:
$$y = x - 18$$
3. **Interpret the slope-intercept form:**
The line has slope $1$ and y-intercept $-18$.
4. **Find the x-intercept:**
Set $y=0$:
$$0 = x - 18 \implies x = 18$$
So the line crosses the x-axis at $(18,0)$ and the y-axis at $(0,-18)$.
5. **Match with the graphs:**
- Graph A: y-intercept $18$, x-intercept $-18$ (does not match)
- Graph B: y-intercept $-18$, x-intercept $36$ (x-intercept does not match)
- Graph C: y-intercept $-18$, x-intercept $-18$ (x-intercept does not match)
- Graph D: y-intercept $-18$, x-intercept $18$ (matches exactly)
**Final answer:** Graph D represents the equation $2x - 2y = 36$.
