Formula: For distance d=( x2-x1)2 +( y1-y2)2.
25. C (-3,-1), Q(-2,3)
Label frist: x1=-3, y1=-1 , x2=-2,y2=3
Second plug the problem in: d=(-2 -(-3))2 + ( -1-3)2
Third solve: d= (5)2 + (-4)2
d= 25+16
d=42
Formula: For midpoint M=(x1+x2,y1+y2) DIVIDE BY 2.
34. T(3,1), U(5,3)
Label frist: x1=3,y1=1, x2=5,y2=3
Second plug the problem in: M=( 3+5 , 1+3)
DIVIDE BY 2
Third solve: M= ( 8/2 , 4/2)
M= (4,2)
