Can somebody pls help me some these two problems by system of equations by graphing . y= -3x + 4
y= 3x = -4

pls hurry i need them!

If the second graph is y = 3x - 4 below answer holds.

If the second graph is y + 3x = -4 then there is no solution.

the intersection is at (4/3, 0).

Step-by-step explanation:

If you add them, you get:

2y = 0 => y=0

then you get

3x = 4 so

x = 4/3

So the intersection is at (4/3, 0).

See graph

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
