Answer:
-20n/3n
Step-by-step explanation:
-4 1
--- / ---
9n 15n
Keep, change, flip
- Keep the -4/9n
- Change the division sign to a multiplication sign
- Flip the 1/15n to 15n/1
-4 15n
--- * ---
9n 1
Cross simplify.
9n divided by 3 is 3n.
15n divided by 3 is 5n.
-4 5n
--- * ---
3n 1
-4 times 5n equals -20n
3n times 1 equals 3n
-20n
---
3n
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b".
If you look at the graph, when x = 0, y is 1, so the y-intercept is 1.
y = mx + 1
To find "m", you can use the slope formula and find two points on the graph and plug it in, or you can use this:
Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right.
If you look at the graph, from each point you go up 1 unit, and to the right 1 unit. So your slope is 
or 1
y = 1x + 1
y = x + 1
To find this, simply subtract 57 from 90. 90 is the measurement for a completed compliment equation, and 57 is the part of the compliment we know.
33 is the answer
The outlier is the number that’s farther away from the others, in this case it’s 9. The mean is the average of all the data points so it is 77/20 or 3.85. Finally, the range is the highest number minus the lowest number, so the range is 8.
