Answer:
I gave you most of the answer. I'll let you check my work and find the point using the solution.
Step-by-step explanation:
The first thing we do is we divide by negative one in the first equation to get
y = -x.
-3x + 3y = -36
Plug in y = -x and get
-3x + 3(-x) = -36
= -3x - 3x = -36
This equals -6x = -36
divide both sides by -6 and you get 6. 6 is your x value
Plug 6 back in to the second equation.
-3x + 3y = -36
-3(6) + 3y = -36
-18 + 3y = -36
3y = -18
y = -6
Answer:
(-1,-4)
Explanation:
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
1. ( -1,2) is the same as (x=-1, y=2)
Substitute in your equation
y=3x-2
2=3•(-1)-2
2=-5 this is NOT true so (-1,2) is not a solution for the equation y=3x-2
2. (0,-2)
9x-6=3y
9(0)-6=3•(-2)
-6=-6 this is true so ( 0, -2) is a solution for the given equation
