# How do you find the slope and intercept of y=x+4?

You can find the slope of a function by looking at the coefficient of $x$ in an equation. In case you forget what the coefficient is, it's the number multiplied by $x$ in the equation. Here, the coefficient is $1$ ... even though it's not written! Because any number multiplied by $1$ does not change, we simplify the writing of $1 x$ as simply $x$. Had this equation been $y = 3 x + 4$ the slope would be $3$.
As for the intercept, to find that, set $x = 0$. In our equation this becomes $y = 0 + 4$ and simplifies to $y = 4$ - that's it!
