Can you show me a graph for the slope of these lines?
-----------------
slope is change in y over change in x.
------------
(a) 1/2
Put your pencil on (0,0)
Since 2 in in the denominator move your pencil 2 to the right
then, since 1 is in the numerator, move your pencil one up:
put a dot at that point. Draw a line thru (0,0) (2,1)
That is a line with slope = 1/2:

------------------------
(b) -2= -2/1
Start at (0,0); move 1 to the right; move 2 down
Draw a line thru (0,0) (1,-2)

------------------------
(c) -1/2
Start at (0,0); move 2 to the right; move 1 down
Draw a line thru (0,0) (2,-1)

--------------------------
(d) 2 = 2/1
Start at (0,0); move 1 to the right; move 2 up
Draw a line thru (0,0) (1,2)
