Answer:
x=4
Step-by-step explanation:
No slope means slope is undefined --> you have vertical line that passes through (4,-6), where x=4, y= -6
We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:
4.27 - 4 = 0.27
Now we can set up a proportion to find the percentage.

Solve for x
0.27 x 100 = 27
27/4 = 6.75
The answer is
6.75% :)

Answer:
i think its x = -14/19 Not 100% sure
X + y = -10
-3x -y = 2
We'll try with x as a small number and y with a big number to try and balance it out.
-3 - 7 = 10
9 - 7 = 2
X = -3
Y = -7
Hope this helps! :)
