The axis of symmety is the x value of the vertex

to find the x value of the vertex of ax^2+bx+c=0
x value=-b/2a

3x^2+bx+4=0
3/2=vertex

-b/2(3)=3/2
-b/6=3/2
times 6
-b=18/2
-b=9
times -1
b=-9

C. Write an equation of the line that contains the given point and has the given slope. Write the equation in slope intercept fo

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

For the first problem, we can plug in the slope of $-5$ for $m$ :

$y = -5x + b$

To solve for $b$ , we plug in the given point $(-2, 2)$ :

$2 = -5(-2) + b$

$2 = 10 + b$

$b = -8$

This gives us the equation:

$y = -5x -8$

For the second problem, we can plug in the slope of $1$ for $m$ :

$y = x + b$

To solve for $b$ , we plug in the given point $(0, -2)$ :

$-2 = 0 + b$

$b = -2$

This gives us the equation:

$y = x - 2$
