53.35/11 = 4.85 for 1 key chain
4.85 *4 = 19.40
Anything between -3≤x<3
Those integers can be -2,-1,0,1 or 2
Answer:
#1. 105.5 because of the nine 4 goes to 5
#2. 67,990,000 because of the 4 it doesn't go up
#3. -4.1 because of the 4 the 0 goes to 1
if the number place before the one you are rounding is 5,6,7,8,or 9you go up by one and the rest becomes zeros
if the number place before the one you are rounding is 0,1,2,3,or 4 you stay the same and the rest becomes zeros
The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is
or:

Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:


Therefore the slope is 1.
