Answer 2

test the points out to see if the equation is true
(x,y) = (3, -8)

3*3 - (-8)/4 = 9 + 2 = 11
true

that point works, try the second one the same way

Answer 3

ok what next? @DanJS

Answer 5

Uh is this middle school math?

Answer 6

yes @LoveIt

Answer 7

do the same thing i did for the first point

Answer 8

i did

Answer 9

(x,y) = (4,4), does it work

Answer 10

no?

Answer 11

3*x - y/4 = 11

for point (x,y)=(4,4), put x=4, and, y=4 into that, see if it remains true or not
