In analyzing a line graph, why is slope important?

The slope of the line reflects the actual trend of the data

Step-by-step explanation:

The options of the question are

a. The slope should be negative.

b. The spacing for each axis must be chosen so that the line reflects a positive slope.

c. The slope of the line reflects the actual trend of the data.

d. The slope of a line is not important in analyzing a line graph

we know that

The slope of a line is the steepness of the line ( the change in 'y' over the change in 'x',)

The formula to calculate the slope between two points is equal to

where

 ---> is called the rise

 is called the run

Is important because the slope of the line reflects the actual trend of the data

i hope this is what you were looking for.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
