To calculate the slope of the line of fit in the scatter plot, we need to select two points on the line and use the formula for slope, which is "change in y" divided by "change in x."
Let's use the ordered pairs (0,3) and (10,8) that are given to us.
The change in y is the difference in the y-values of the two points: 8 - 3 = 5.
The change in x is the difference in the x-values of the two points: 10 - 0 = 10.
Now, we can calculate the slope by dividing the change in y by the change in x:
Slope = (change in y) / (change in x) = 5 / 10 = 0.5.
Therefore, the slope of the line of fit is 0.5.
