Given system%28y=-6%5E2%2B3x%28EQN1%29%2C+y=-3x-6x-1%28EQN2%29%29
In EQN1,
y=36%2B3x, wheresystem%28Slope=m=3%2CyIntercept=36%29
Let fy=0
0=36%2B3x ---> 3x=-36 --->cross%283%29x%2Fcross%283%29=cross%28-36%2912%2Fcross%283%29 ---> red%28x=-12%29, X-Intercept
Let fx=0 ----> y=36%2B3%280%29=red%2836%29, Y-Intercept
See graph,



In EQN2,=> y=-3x-6x-1
y=-9x-1, wheresystem%28SLope=-9%2CyIntercept=-1%29
Let fy=0
0=-9x-1 ----> 9x=-1--->red%28x=-1%2F9%29, X -Intercept
Let fx=0
y=-9%280%29-1=red%28-1%29, Y-Intercept
See graph,

Thank you,
