Question

Help me with this problem

Answer 1

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.

We then plug in the values and solve

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

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

$A = 28\ units^2$

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

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