Question

Help me find the figure , area formula and graph the dots and find the area

Answer 1

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
