select 2 points from the triangles that form the line
it can be point A=(-6,-2) and ponint E=(3,1)
use the formula for the slope
![\begin{gathered} m=\frac{y2-y1}{x2-1} \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20m%3D%5Cfrac%7By2-y1%7D%7Bx2-1%7D%20%5C%5C%20%20%5Cend%7Bgathered%7D)
replace the values
![\begin{gathered} m=\frac{1-(-2)}{3-(-6)} \\ m=\frac{3}{9}=\frac{1}{3} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20m%3D%5Cfrac%7B1-%28-2%29%7D%7B3-%28-6%29%7D%20%5C%5C%20m%3D%5Cfrac%7B3%7D%7B9%7D%3D%5Cfrac%7B1%7D%7B3%7D%20%5Cend%7Bgathered%7D)
the slope for the line shown is 1/3
The answer would be D just took test
I believe that The answer is 8feet
x= -35/11
1) distribute, -9x -63x = 13x+7
2) put like terms on the same side of parentheses, -9x -13x= 7+63
3) combine like terms, -22x = 70
4) solve for x, x= -70/22
5) simplify, x= -35/11
By adding x = -7 so (4*-7-8y=0) y=(-7/(8*4))=3.5
