Anyone know how to use regressions for this problem? I thought I would for sure get it right. I set the diamond equal to b and the star equal to c, then made a list regression for both equations up top. once my regression solved for b and c, I plugged those values into the solution we wanted the answer choices to equal to. desmos spat out a random number, and i typed in ewvery equation to see which one would give me the same value. That equation was A. How is this wrong?
