The slope of the line should be 2 because when using rise over run for the graph it is shown that the slope rises 2 and runs 1 meaning the fraction is 2/1 which when simplified is 2
Answer:

Step-by-step explanation:
When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line,
.
To obtain the slope from the line AB, we need two points, so the general equation will be:

The typical equation of a line is written as y = mx + b
The second line will pass through point (2, -1), so we can substitute:
y2 = mX2 + b
-1 =
(2) + b
then the interception is 
Now to obtain a general equation for the second parallel line will be:
y =
X + b
y =
X -
(2)-1
Finally we get:
y =
(x-2)-1
3141.6 cubic meters
Step-by-step explanation:
The volume of a cylinder is given by;
πr²h
π * (²⁰/₂)² * 10
π * 100 * 10
= 3141.6
Pat attention to the ending of the numbers. If there are an odd amount of odds, it's going to be odd. If there is an even amount of odds, it's going to be even. If there's only evens, it's only going to stay even.
