A line passes through points (2, 1) and (4, 3). Where does the line intersect the xaxis?
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?

Under root (X2X1) the whole square +(Y2Y1) the whole square.
Under root (1(7))whole square + (411)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
ANSWER IS 17. 
1/2Ix1(y2y3)+x2(y3y1)+x3(y1y2)I
1/2I0(16)+3(60)+(2)(01)I
1/2I0+182I
1/2I16I
