danjs · Answer

just plug in (a,b)=(4,0) or the other 3 and see which one equals 28

michele_laino · Answer

please you have to substitute all of your pairs into your equation

danjs · Answer

7(4) - 5(0) = 28

Thanks Dan

jordanloveangel · Answer

try plugging the points, example first point you have (0,4)
7a - 5b = 28
7(0) - 5(4) = 28
 0  - 20 = 28
     -20 = 28
