Use the image to answer the question.
A triangle is graphed by joining three plotted points on the first quadrant of a coordinate plane. The x and y axes range from 0 to 10 in increments of 2.
What is the area of the triangle in square units?

I can't see the image yet. Could you either upload the picture or tell me the coordinates of the three plotted points? (They will be the grid intersection values like (x,y).)
If you want to solve it yourself, here are two quick methods:
1) If the triangle has a horizontal side and a vertical side (right triangle aligned to axes):
- Area = (base × height) / 2, where base and height are the horizontal and vertical distances between the appropriate vertices.
2) General case (any three vertices): use the shoelace formula.
- If vertices are (x1,y1), (x2,y2), (x3,y3) in order, area = 1/2 × | x1*y2 + x2*y3 + x3*y1 − (y1*x2 + y2*x3 + y3*x1) |.
If you give the three coordinates I will compute the exact area and pick the correct choice.
