Just sub the coordinates of each point into the equation to see if it satisfies
the equation.
I will do (-4,9)
LS = 2x + y
= 2(-4) + 9
= 1
RS = 1, Ahhh, the point (-4,9) is one of the points that lie on the line
Repeat for the others.
The graphing should be simple
Determine which three out of the six points shown below are a solution to the equation 2x + y = 1. Plot the three points that are in the solution set, draw a line through the three points, and then answer the questions below.
(2,-3), (0,-4), (-2,-5), (5,-9),(-4,9),(6,-1)
