Question

to determine the equation of his line of best fit, he must first identify the ____ of two points on the line.

coordinates

compositions

compromises

rewatch

Explanation:

To find the equation of a line (including the line of best fit), we need the coordinates of points on the line. Coordinates (x, y values) of two points are used to calculate the slope (via the slope formula $m=\frac{y_2 - y_1}{x_2 - x_1}$) and then the equation. "Compositions" refers to combining elements (not related to lines), and "compromises" is about agreements, so they don't fit.

Answer:

A. coordinates
