Answer is (4,3)
=============================
Add up the x coordinates to get 9+(-1) = 8. Divide this over two and we end up with 8/2 = 4
Repeat for the y coordinates: 9+(-3) = 6, which cuts in half to get 6/2 = 3
The midpoint is at (4,3)
-------
The midpoint formula is
where (x1,y1) and (x2,y2) are the endpoints.
Answer:
x = - 16
Step-by-step explanation:
The equation relating two proportional quantities is
y = kx ← k is the constant of proportionality
To find k use the condition when y = 1, x = - 4
k = 
= - 
y = - x ← equation of proportionality
when y = 4, then
4 = - x (multiply both sides by - 4 )
x = - 16

Answer:
28m
Step-by-step explanation:
Find the perimeter
Perimeter=2(length+width)
=2(8+6). =2(14). =28m
