0/9 would be the fraction
First graph your x and y intercept then pick any two points on the line.

that's the equation used to find your slope
Example:
(4,2) (8,6) let's say those are the points you pick from the line
so then you subtract 6-2=4 (6 is your y2 and 2 is your y1)
then subtracts 8-4=4 (8is your x2 and 4 is your x1)
then your left with

if you can reduce the reduce in this case you can which leaves you with

and that's how you find the slope
X-30+x-30+x=180
3x-60=180
3x=240
X=80
tom's snowman has to increase by anything greater than 4.4 ft
You will at 7 to both sides and then divide 2 on both sides to find x. :)
2x-7=3
+7=+7

2x = 10

X = 5
