plug in x and y of each and see if you get -26

for example choice a is the ordered pair (x=-4,y=-4) -2(-4)+9(-4)=8-36=-28 which is not -26 so choice a is not an ordered pair on the line -2x+9y=-26

try d (x=-5,y=-4) -2(-5)+9(-4)=10-36=-26 which equals -26 so (-5,-4) is on the line -2x+9y=-26 d is the correct solution
