Answer:
-5.25 + 3.5 = -1.75
Step-by-step explanation:
This can technically be done two ways. The first is the most simplified, and the second less simplified, and less likely to get the best grade.
1.So long as you don't have to order it chronologically, you should be good with this one: 
2.This one IS chronological (she got a correct answer, then a wrong answer), but you can NOT simplify it, because it asks for an addition equation: 
The best option is probably #1
To what place?!?! You need to have a place value to even round a number!!!
But i will guess the place value
32,879 rounded to the nearest thousand is 33,00
The answer is a I believe
Answer:
2.2y-2x = 0
Step-by-step explanation:
The standard form of the equation is normally y = mx + c where m is the gradient or the slope value while c is the y intercept.
As we know, the line passes through the origin, hence, it has no y intercept. This means our c has a value of zero.
What is left to find is the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (2 - 0)/(5 - 2.8)
m = 2/2.2 = 0.9091
so the standard form of the equation of the line is y = 0.9091x
OR
y = (2/2.2)x
OR
2.2y = 2x
