The equation you're working with appears to be in the form:

$f(x) = 2x + 6$

Here, $f(x) = 2x + 6$, and you are interested in finding the y-intercept.

To find the y-intercept:

The y-intercept occurs where $x = 0$, meaning you substitute $x = 0$ into the function:

$f(0) = 2(0) + 6 = 6$

Thus, the y-intercept is $6$. This means the graph crosses the y-axis at $(0, 6)$.
