### Example Question #2 : X Intercept And Y Intercept

What is the y-intercept of the following line:

**Possible Answers:**

**Correct answer:**

To find the y-intercept, we will look at the slope-intercept form of a line:

where *m* is the slope and *b* is the y-intercept.

So, given the equation

we can see the y-intercept is -11. Note that we must include the negative sign.
