If the two angles are supplementary, they must equal 180 degrees
Answer:
Use the formula y-y1=m(x-x1) <---memorize this. The m here is the slope.
Step-by-step explanation:
The equation is in y=mx+b form
Remember mx=slope and b=y-intercept
The question wants you to find the equation that is Parallel to y=-3x-2 and passes through (-3,-3)=(x1,y1)
Parallel=same slope -3x
So now all that's left is to plug into the equation.
y-(-3)=-3(x-(-3))
y+3=-3(x+3) ----> positive - a negative = positive so x-(-x)=x+x
y+3=-3x-9 ----> distribute like terms(subtract 3 from 3 and 3 from -9)
y=-3x-12 - This is your answer, you can check by graphing it.

Answer:
(- 2, 0 ), (1, 0 )
Step-by-step explanation:
Given
y = 2x² + 2x - 4
To find the x- intercepts let y = 0, that is
2x² + 2x - 4 = 0 ← divide through by 2
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 1 = 0 ⇒ x = 1
Thus x- intercepts are (- 2, 0) and (1, 0)
