Answer:
undefined
Step-by-step explanation:
![\boxed{slope = \frac{y1 - y2}{x1- x2} }](https://tex.z-dn.net/?f=%5Cboxed%7Bslope%20%3D%20%20%5Cfrac%7By1%20-%20y2%7D%7Bx1-%20x2%7D%20%7D)
☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.
Slope of the line

Notice that the 2 points have the same x-coordinate of -1, which means that the line is a vertical line. Vertical lines have an undefined slope.
Answer:
The total change that will likely occur in 2 years is
mg/L
Step-by-step explanation:
Given : The first year, they found the chloride concentration changed by
mg/L .
It is estimated that the chloride concentration will change
mg/L the next year.
To find : What is the total change that will likely occur in 2 years?
Solution :
The chloride concentration changed by
mg/L in first year.
The chloride concentration will change
mg/L the next year.
The total change that will likely occur in 2 years is
In a mixed fraction -
mg/L
Answer: The slope of the line perpendicular to y=41 is not defined.
The slope of the line parallel to y=41 is 0.
Step-by-step explanation:
Given equation of line: y=41
When we plot it on the graph parallel to the x axis, and we know that slope of x axis is 0. [by using slope formula]
Therefore, the slope of y=41 must be 0[slope of parallel lines are equal]
Now, any line perpendicular to y=41 must be in the form of x=a, where a is any integer .
We know that x=a is a vertical line and is parallel to y axis, thus its slope must be not defined.[because slope of y axis is not defined]
