Mathematics

Answer:

Looking at the given points we know that it is going to be a triangle because it only have 3 points.  Therefore the figure is a triangle and the area formula would be A=\frac{1}{2}*b*h.

You can look at the attached graph and what we see is that our height of the triangle is from y=-3 to y=4 which means that our height is 7 units high.  We can also see that our base starts at x=-4 and ends at x=4 making us have a base of 8 units.

<u>We then plug in the values and solve</u>

A = \frac{1}{2}*7\ units * 8\ units

A = \frac{1}{2}*56\ units^2

A = 28\ units^2

Therefore, the area of our triangle is 28\ units^2

Hope this helps!  Let me know if you have any questions
