OK so in the first scenario you said "Start by choosing any three values for x" so I tried a random -4, 9, and 0 to see if it would make a straight line but the points don't all line up - so does that mean that the three values you choose have to be among a set of specific numbers, or did I do something wrong?
You're correct that you can choose any three values for X when graphing a linear equation by plotting points. As long as the calculations are done correctly, the points will always line up and form a straight line. For the values you mentioned (-4, 9, and 0), here are the corresponding points you should have gotten: (-4,-11) ; (9,15) ; (0,-3). If your points didn't line up, double-check the calculations and make sure to plot them accurately on the graph. Let me know if you need further help!
Thanks a lot professor for your efforts. I follow you from Algeria.
