Question

In analyzing a line graph, why is slope important?

Answer 1

Answer:

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

$m=\frac{y2-y1}{x2-x1}$

where

$y2-y1$  ---> is called the rise

$x2-x1$  is called the run

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