Hi there!
Let's first determine the x-intercept. When dealing with an x-intercept we must realise the y-coordinates equal 0.
Add 21 to both sides.
Divide both sides by -2.
Therefore, the x-intercept is the point (10 1/2; 0).

Now let's continue with the y-intercept, which is easier. When dealing with an y-intercept we must realise the x-coordinates equal 0.
Therefore, the y-intercept is the point (0; -21).
