So for the 1st and 3rd ones (the graphs), all you have to do is find which y matches the x value of 0
The 2nd one is a bit harder. I’ll explain it the best I can
So in the y section, you see that -4 goes to -3 when the x is raised by 1. There for everytime the x raises by 1, so does the y. That means when x = 0, the y = -2
A=3B 4.35A+5.40B=780.95 Substitute 3B into A for the second equation: 4.35(3B)+5.40B=780.90 13.05B+5.40B=780.90 18.45B=780.90 B=42.33 Plug into equation 1: A=3B A=3(42.33) A=126.98
