Answer:

Step-by-step explanation:

we have

y=2x2-8x+9

Group terms that contain the same variable, and move the constant to the opposite side of the equation

y-9=2x2-8x

y-9=2(x2-4x)

y-9+8=2(x2-4x+4)

y-1=2(x2-4x+4)

y-1=2(x-2)2

y=2(x-2)2+1

the answer is the option C

y=2(x-2)2+1

Q # 9 help please:The table shows the height of a plant as it grows.What equation in point-slope form gives the plant's height a
ivanzaharov [21]

Answer: First option. y-15=5(x-3)

Solution:

We can take any pair of points of the table. For example:

P1=(3, 15)=(x1, y1)→x1=3, y1=15

P2=(5, 25)=(x2,y2)→x2=5, y2=25

And we can find the slope m using the following formula:

m=(y2-y1)/(x2-x1)

m=(25-15)/(5-3)

m=(10)/(2)

m=5

Now we can apply the point-slope formula to find the equation of the right line:

y-y1=m(x-x1)

Replacing y1=15, m=5, and x1=3

y-15=5(x-3)
