Below are the choices that can be found elsewhere:
A. rectangle; P = 26 linear units
B. square; P = 42 units2
C. parallelogram; P = 42 linear units
D. trapezoid; P = 26 linear units
The answer would be A.
To find the slope of a line, we can use the following formula:
![\displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%7D)
m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.
Let these be the following:
![\displaystyle \large{(x_1,y_1) = (0, - 11)} \\ \displaystyle \large{(x_2,y_2) = (8, - 8)}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7B%28x_1%2Cy_1%29%20%3D%20%280%2C%20-%2011%29%7D%20%5C%5C%20%20%5Cdisplaystyle%20%5Clarge%7B%28x_2%2Cy_2%29%20%3D%20%288%2C%20-%208%29%7D)
Substitute the points in formula:
![\displaystyle \large{m = \frac{ - 8 -( - 11)}{ 8 - 0} }](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%20%5Cfrac%7B%20-%208%20-%28%20-%2011%29%7D%7B%208%20-%200%7D%20%7D)
Negative multiply negative always come out as positive.
![\displaystyle \large{m = \frac{ - 8 + 11}{ 8 - 0} } \\ \displaystyle \large{m = \frac{ 3}{ 8 } } \\](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%20%5Cfrac%7B%20-%208%20%20%2B%20%2011%7D%7B%208%20-%200%7D%20%7D%20%5C%5C%20%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%20%5Cfrac%7B%203%7D%7B%208%20%7D%20%7D%20%5C%5C%20)
Since m stands for slope, we can say that:
![\displaystyle \large \boxed{ \tt{slope = \frac{3}{8} }}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20%20%5Clarge%20%5Cboxed%7B%20%5Ctt%7Bslope%20%20%3D%20%20%5Cfrac%7B3%7D%7B8%7D%20%7D%7D)
