# 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 = (y_{2} - y_{1})/ (x_{2} - x_{1})

Where m is the slope of the line.

x_{1}, x_{2} are the coordinates of the x-axis, and

y_{1}, y_{2} 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.
