The vertex of this parabola is at (-2,-3). When the y-value is -2 the x-value is -5. What is the coefficient of the square term
olchik [2.2K]

Answer:

a = -3

Step-by-step explanation:

You're correct.

The form of the equation you need is

x=a(y-k)^2+h

Filling in our h, k, y, and x:

-5=a(-2+3)^2-2 which simplifies to

-5=a(1)-2 which simplifies further to

a=-3

Very good!!!! These can be tricky, but you got it!!

Math help again please
vovangra [49]
Hey there! :D

First, find the slope. 

m= (y2-y1)/(x2-x1) I'm using points (0,3) and (1,5)

m=(5-3)/(1-0)
m= 2/1
m=2

Now, plug that into point slope. Use point (1,5) m=2

y-y1= m(x-x1)

y-5= 2(x-1)

Distribute. 

y-5=2x-2

Add 5 to both sides.

y=2x+3 == equation of the line in slope intercept form. y=mx+b

I hope this helps!
