Explanation:
You divide for the first one. for example, 3/18, u divide it with 3. 18÷3 is 6, so you divide the same the number. so it will be 1/6. so F, is 1.
for the other one, you polt the points and then connect it, but then when it says Stop, you have to stop and start a new a one. lemme show u an example.
(-3,-11)
-3 is the X axis
and -11 is the y axis
the vertical line is the y axis and the horizontal line is the x axis
