Truthfully, this is tough to type over a computer but, let me see if I can guide you through doing it.
Method: Starting from the very center of the graph, move according to the coordinates, using (x, y)
- X is your horizontal axis.
- Y is your vertical axis.
Concept of Understanding Negatives and Positives:
A positive X, will mean it goes to the right.
A positive Y, will mean it goes up.
A negative X, will mean it goes to the left.
A negative Y, will mean it goes down.
Apply!
- From the center, "A (-2 , -1)" will translate to "go left two spaces, and go down by one". Plot the point.
- From the center, "B (-3 , -1)" will translate to "go left three spaces, and go down by one". Plot the point.
- From the center, "C (3 , 3)" will translate to "go right three spaces, and go up by thjree". Plot the point.
- From the center, "B (-2 , 3)" will translate to "go left two spaces, and go up by three". Plot the point.
CONNECT THE LINES! :D
Next, let's find the area of that shape!
Area = Base×Height
In this case, 4×1, because the height is 4 boxes, and it's 1 box for it's base.
