What is the slope of a trend line that passes through the points (-3, 3) and (18, 26)?

Solution:

The slope formula refers to the formula used to calculate the steepness of a line and determines how much it's inclined.

To calculate the slope of the lines, the x and y coordinates of a line are used.

The formula to calculate slope is given as,

m = (y₂ - y₁)/ (x₂ - x₁)

Where m is the slope of the line.

x₁, x₂ are the coordinates of the x-axis, and 

y₁, y₂ are the coordinates of the y-axis.

The points given are (-3, 3) and (18, 26)

Substituting it in the formula

m = (26 - 3)/(18 - (-3))

m = 23/(18 + 3)

m = 23/21

Therefore, the slope of the trend line is 23/21.

What is the slope of a trend line that passes through the points (-3, 3) and (18, 26)?

Summary:

The slope of a trend line that passes through the points (-3, 3) and (18, 26) is 23 / 21.
