To solve the equation \( \frac{9x - 5}{3x + 1} = 4 \) by graphing, first rewrite the equation in a suitable form for graphing: 1. Rearrange the equation: \( 9x - 5 = 4(3x + 1) \) 2. Expand the right side: \( 9x - 5 = 12x + 4 \) 3. Move all terms involving \( x \) to one side and constants to the other: \( 9x - 12x = 4 + 5 \) which simplifies to \( -3x = 9 \) 4. Divide by -3: \( x = -3 \) Now, to graph it, plot the equation \( y = \frac{9x - 5}{3x + 1} \) and the line \( y = 4 \). The intersection of these two graphs will give the solution, which is \( x = -3 \). You can use graphing tools like Desmos or even graph it on paper to visualize how both functions interact and identify where they meet! And voilà, you now have a clear and engaging way to find the solution by graph!
