Example Question #1531 : Intermediate Geometry

Find the x-intercept of the line .

Possible Answers:

Correct answer:

Explanation:

Start by putting the equation into  form, where  is the slope, and  is the y-intercept.

By definition, the x-intercept is where the line crosses the x-axis. As such, the y-coordinate of this point must be 

Plug  in for  in the equation for this line.

Now, solve for .

The x-intercept is found at .
