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=(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.

We then plug in the values and solve


A = (1)/(2)*7\ units * 8\ units


A = (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
