Solve each system graphically.
#6.
4x  y = 9
x  3y = 16
I need to find at least one pair of points that fit. I tried using the elimination method and got (5 and 6/7, 22), which did not even work for the first equation.
I also tried graphing it but it was too hard to tell.
Can anyone help me with solving this?
Thanks so much! :)

you can try substitution
y=4x9
x3(4x9) = 16
x  12x + 27 = 16
11x=11
x=1
4y=9
y=5
(1,5)

Didn't your question ask for a graphical solution?
so you have to find at least 2 ordered pairs for each equation and then draw them
for the first:
4x  y = 9 > y = 4x  9
x y
1 5
3 3
for the second:
x  3y = 16 > x = 3y + 16
x y
4 4
2 6
graph both lines, they should intersect at (1,5), the answer chopsticks gave you.
