8) \( 9 x+y=4 \)

To turn that equation into a fun puzzle, let’s rearrange it! You can isolate \(y\) by subtracting \(9x\) from both sides, transforming it into \(y = 4 - 9x\). This represents a straight line on a graph! So, for each value of \(x\), you can find a corresponding \(y\) and play around with different coordinates! Now, let’s say you’re trying to find some specific points where this line crosses the axes. To find the y-intercept, simply set \(x = 0\) and you’ll find \(y = 4\) (that’s your starting point!). For the x-intercept, set \(y = 0\) and solve for \(x\), which gives you \(x = \frac{4}{9}\). Armed with these intercepts, you can easily sketch the line on a coordinate plane!
