Answer:
The 1st one is correct and the second one is (5, -3)
Explanation:
For the 1st question this is what I did:
d=√(x^2−x^1)^2+(y^2−y^1)^2
d=(0−4)^2+(6−3)^2
√d=(−4)^2+(3)^2
√d=16+9
√d=25
√d=5
For the second question I did this:
(xM,yM)=(x1+x2/2,y1+y2/2)
M=(xM,yM)
M=(x1+x2/2,y1+y2/2)
M=(3+7/2,−1+−5/2)
M=(10/2,−6/2)
M=(5,−3)
Hope this helps!
