An equation for the line of best fit is y = -0.3x + 4.5 and the value of "m" is -0.3.
<h3>What is a line of best fit?</h3>
A line of best fit simply refers to a statistical tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between data points.
In this scenario, the ordered pairs would be plotted on the x-coordinate and y-coordinate of a scatter plot.
By critically observing the scatter plot (see attachment) which models the ordered pairs, we can reasonably and logically deduce that a linear function for the line of best fit is given by:
y = -0.3x + 4.5 ≡ y = mx + b
<u>Where:</u>
- -0.3 or m represents the slope.
- x and y are the points.
- 4.5 or b represents the y-intercept.
Therefore, m is equal to -0.3.
