Find the midpoint of PQ if P(-7, 11) and Q(1, -4).
Find the area of the rectangle with vertices B(8, 0), T(2, -9), R(-1, -7) and C(5, 2).
Find the area of a triangle with vertices (0, 0), E(3, 1) and F(-2, 6).
Given a rhombus with points E(-4, 1), F(2, 3), G(4, 9) and H(-2, 7), find the slopes of the diagonals.
A line passes through points (-2, -1) and (4, 3). Where does the line intersect the x-axis?

I will be happy to critique your thinking and work on this. I wont do if for you.

Send you the answerx?? Who exactly is getting the education here? :)
Give us some idea where the difficulty is and what you've tried. We'll give advice then. K?

• coordinate geomoetry -

Under root (X2-X1) the whole square +(Y2-Y1) the whole square.
Under root (1-(-7))whole square + (-4-11)whole square.
Under root (1+7)whole square + (-15)whole square.
Under root 8 square + 225
Under root 64 + 225
Under root 289
square root of17 is 289
SO ROOT OF 289 IS 17
