The answer to this question is -3/35
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).
Three sides, because if you make a clean cut the surface of the cut is a triangle.
