To solve the equation $y = mx + b$ for $x$, follow these steps:

1. Subtract $b$ from both sides of the equation: $y - b = mx$

2. Divide both sides of the equation by $m$: $x = \frac{y - b}{m}$

Thus, the solution for $x$ is: $x = \frac{y - b}{m}$

Here are 5 related questions you might find interesting:

1. What happens if $m = 0$ in the equation $y = mx + b$?
2. How would you interpret $m$ and $b$ in the context of a graph?
3. Can you rewrite $y = mx + b$ in a different form, like slope-intercept form?
4. How do you find the slope $m$ if given two points on a line?
5. How do you calculate the $x$-intercept from the equation $y = mx + b$?

Tip: Always check for special cases like $m = 0$, which results in a horizontal line.
