Question: Graph the equation $3x+5y=30$
1. **State the problem:** We need to graph the linear equation $$3x + 5y = 30$$.
2. **Rewrite the equation in slope-intercept form:** To graph easily, solve for $y$:
$$3x + 5y = 30$$
Subtract $3x$ from both sides:
$$5y = 30 - 3x$$
Divide both sides by $5$:
$$y = \frac{30 - 3x}{5}$$
Show cancellation:
$$y = \frac{\cancel{30} - 3x}{\cancel{5}}$$
Simplify:
$$y = 6 - \frac{3}{5}x$$
3. **Identify slope and intercept:**
- Slope $m = -\frac{3}{5}$
- $y$-intercept $b = 6$
4. **Find intercepts:**
- $y$-intercept: When $x=0$, $y=6$.
- $x$-intercept: When $y=0$, solve $3x + 5(0) = 30 \Rightarrow 3x=30 \Rightarrow x=10$.
5. **Plot points:**
- Plot $(0,6)$ on the $y$-axis.
- Plot $(10,0)$ on the $x$-axis.
6. **Draw the line:** Connect these two points with a straight line. This is the graph of the equation.
**Final answer:** The graph is a straight line passing through points $(0,6)$ and $(10,0)$ with slope $-\frac{3}{5}$.
