What is the area of a triangle with vertices at open paren negative 3 comma 3 close paren , open paren 2 comma 3 close paren , and open paren 4 comma 7 close paren ?

The points (−3, 3) and (2, 3) form a horizontal base of length 2 − (−3) = 5 units. The third point is 4 units above that base, so the triangle’s area is ½ × 5 × 4 = 10 square units. The correct choice is 10 square units.
