Answer:
11. -3/2
12. -1
Explanation:
To find slope, subtract the y's and put that on top of a fraction. Then subtract the x's and put that on the bottom of the fraction. Simplify if you can.
Subtract y's 2 - -4 is
2+4 which is 6, put that on top.
0 - 4 is -4 put it on the bottom.
Slope is 6/-4. Simplified, this is -3/2
The other question, same thing:
y-y over x-x
-4 - -3 / -2 - - 3
= -4+3 / -2 + 3
= -1 / 1
= -1
