Simplify the slope of AC

Answer:
[tex]Slope\:\: \overline{AC} =1[/tex]
Step-by-step explanation:
A is on the same point on the x-axis as B and the same point on the y-axis as D
C is on the same point on the x-axis as D and the same point on the y-axis as B.
We are to determine the slope of the line joining A to C.
[tex]Slope, m =\dfrac{y_2-y_1}{x_2-x_1} \\(x_1,y_1)=(0,0),(x_2,y_2)=(a,a)\\$Therefore, Slope of AC$\\m =\dfrac{a-0}{a-0}\\=\dfrac{a}{a}\\\\=1[/tex]
[tex]Slope\:\: \overline{AC} =1[/tex]
