I seriously need help! Tutor please?

ABC has vertices A (0, 0), B (2, 2), and C (5, -1). Find the coordinates of L, the midpoint of AC, and M, the midpoint of BC. Verify that LM AB and LM= 1/2 AB.

First can you try to draw a figure for better understanding?

anonymous · Answer

you must use the midpoint formula

anonymous · Answer

Yeah |dw:1450276936701:dw|

anonymous · Answer

isnt that y=mx+b?

anonymous · Answer

no

aravindg · Answer

See if (a,b) , (c,d) are 2 of the vertices.

Then the midpoint is given by

( (a+c)/2, (b+d)/2 )

anonymous · Answer

m= y2-y1/x2-x1?

But there is no d coordinate

anonymous · Answer

this is the formula you must plug in your own numbers

anonymous · Answer

I think I got it. 

 L (5/2, -½), M (7/2, ½). AB slope = 1 and LB slope = 1 also. So LM= ½ AB

Is that right?
