Considering the given scatter-plot, the line of best-fit is given by:
y = 0.77857t + 3.7.
How to find the equation of the line of best-fit using a calculator?
To find the equation, we need to insert the points (t,y) in the calculator.
In this problem, considering the scatter-plot, we have that:
- The values of t are: 1, 2, 3, 4, 5, 6, 7.
- The values of y are: 3.8, 5.8, 6.2, 7.5, 7, 8.2, 9.2.
Hence, using the calculator, the equation is:
y = 0.77857t + 3.7.
