Answer:
-18+20=2 so (2,4) is a solution
Step-by-step explanation:
to be able to figure out if the ordered pair is a part of solution, only need to input the x value and see if you can get the output which is y
-9x+5y=2 for (4,2)
-9(4)+5(2) does not equal 2
for :(3,4)
-9(3)+5(4)=2
-27+20 does not equal 2
for (4,3)
-9(4)+5(3)=
-36+15 no solution
for : (2,4)
-9(2)+5(4)=
-18+20=2 so (2,4) is a solution
