Understanding Points on a Line

The video tutorial explains how to determine if given points lie on the line y = -x + 3 by substituting the x-coordinates into the equation and checking if the resulting y-values match the given y-coordinates. The process is demonstrated with four points: (-3, 6), (2, -1), (5, 3), and (4, -1). The points (-3, 6) and (4, -1) satisfy the equation and lie on the line, while the others do not. The tutorial concludes with a graphical verification of these results.

What is the equation of the line discussed in the video?

• y = x + 3

• y = -x + 3

• y = 2x - 3

• y = -2x + 3
