Question
Draw the graph of the following linear equations in two variables:
3x + 5y = 15
3x + 5y = 15
✓
Answer
We have, 3x + 5y = 15 ⇒ 3x = 15 - 5y$\Rightarrow\text{x}=\frac{15-5\text{y}}{3}\ ...\text{(i)}$
Putting y = 0, we get $\text{x}=\frac{15-5\times0}{3}=5$ Putting y = 3, we get $\text{x}=\frac{15-5\times3}{3}=0$ Thus, we have the following table giving two points on the line represented by the equation 3x + 5y = 15:
