Example Question #1 : X Intercept And Y Intercept
What is the y-intercept of the following line:
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.
