(B) [tex]\frac{78-87}{8-2}[/tex]
The slope of the trend line:
- A linear relationship is depicted by a trend line.
- [tex]Y=mx+b[/tex], where [tex]x[/tex] is the independent variable, [tex]y[/tex] is the dependent variable, m is the slope of the line and [tex]b[/tex] is the y-intercept, is the equation for a linear relationship.
Scatter plot -
- Data visualization that depicts the relationship between two numerical variables is known as a scatterplot.
- The values for the two variables are used to depict each member of the dataset as a point with [tex]x-y[/tex] coordinates that correspond to those values.
Therefore, (B) [tex]\frac{78-87}{8-2}[/tex] can be simplified to find the slope of the trend line in the scatter plot.
