What are the coordinates of the centroid of a triangle with vertices p(−4, −1) , q(2, 2) , and r(2, −3) ?

Simplify.7x + 3y - 2 + 6x + 1 + y squared 2 you! ; )

Look at attachment. has all info needed. need

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.
