Given: system%28+3x-5y+=+-9%28red%28EQN1%29%29%2C5x-6y+=+-8%28green%28EQN2%29%29%29

In red%28EQN1%29,Let Fx=0
3%280%29-5y=-9
cross%28-5%29y%2Fcross%28-5%29=-9%2F-5
red%28y=9%2F5%29, Y-intercept -> (0,9/5) or (0,1.8)

Let Fy=0
3x-5%280%29=-9 ---> cross%283%29x%2Fcross%283%29=cross%28-9%293%2Fcross%283%29
red%28x=-3%29, X-Intercept (-3,0)

In green%28EQN2%29,
Let Fx=0 ---> 5%280%29-6y=-8
cross%28-6%29y%2Fcross%28-6%29=cross%28-8%294%2Fcross%28-6%293
green%28y=4%2F3%29, Y-Intercept (0,4/3)

Let Fy=0 ---> 5x-6%280%29=-8
cross%285%29x%2Fcross%285%29=-8%2F5
green%28x=-8%2F5%29, X-Intercept (-8/5,0) or (-1.6,0)
----> red%28EQN1%29; green%28EQN2%29
