Do the square root because the sides of a square are always equal and you should get 13 and 14

Answer:
(5,4)
Step-by-step explanation:
multiply each equation by the value that makes the coefficients of x opposite
(-1) · (4x + 6y) = (-1) · 44
4x + 2y = 28
simplify
-4x - 6y = -44
4x + 2y = 28
add the two equations together to eliminate x from the system
-4x - 6y = -44
<u>+ 4x + 2y = 28</u>
-4y = -16
divide each term by -4
y = 4
substitute the value for y into one of the original equations, then solve for x
-4x - 6y = -44
-4x - 6(4) = -44
-4x - 24 = -44
+ 24 + 24
-4x = -20
divide by -4
x = 5
so, since x = 5 and y = 4 ....
the solution to the independent system of equations can be represented as a point.

hope this helps! :)
Answer:
9/5
Step-by-step explanation:
The slope between the two points can be found by ...
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5
The slope of the line is 9/5. Perhaps this is a match to choice A.
