A
Try to figure out the formula for the slope!

Answer 4

Could you explain the formula D:

Answer 5

here goes:
\[slope = (x _{2} - x _{1})\div (y _{2} - y _{1})\]
In this case, \[x _{2} = 3, x _{1} = 4, y _{2} = 1, y _{1} = 2\]

Answer 6

?????? D:

Answer 7

do you see the 3, 4, 1, and 2 in the (4, 2) and (3, 1)?
(4, 2) is the first point, and (3, 1) is the second point.
Do you see why I put the \[_{1 }\]
and \[_{2}\] there?
