anonymous · Answer

A(9, 8) F(8, 7)  and   B(9, 10) C(8, 11)

imstuck · Answer

Those are the coordinates of each of your points, right?

anonymous · Answer

yes and the two segments are AF and BC

imstuck · Answer

Do you know how to find the slope of a line (or a segment) using the coordinates they gave you?

imstuck · Answer

There is a formula for it.$$slope=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }$$

anonymous · Answer

I am not really good at this type of thing. I am trying to help my brother

imstuck · Answer

For the first segment, AF, the coordinates of A are (9, 8) and the coordinates of F are (8, 7).  Subtract the y coordinate of F from the y coordinate of A.  The y coordinate of F is 7, and the y coordinate of A is 8.  What is 7 - 8?

1

imstuck · Answer

Actually, it's -1.  But ok.  Now subtract the x coordinate of F from the x coordinate of A.  the x coordinate of F is 8, and the x coordinate of A is 9.  What is 8 - 9?

anonymous · Answer

-1
