Answer:
The line of best fit for your specific question is a linear equation.
Explanation:
A linear equation has a constant rate of growth/decline and the growth/decline rate will never change in an linear equation.
If you draw a line that approximately splits between all the data plots, you will notice the line you drew is very close to the data points.
If the data plots was a quadratic, it would be very hard to draw a line of best fit.
Linear equations can easily be identified in a graph because it is a straight line.
Perhaps insert this equation into your graphing calculator or other graphing software online (like Desmos): y = 3x+2
A quadratic equation can also easily be identified in a graph because, in most cases, it looks like a U.
Take these examples: y =
or y=
