Answer:

y = 3x - 9

Step-by-step explanation:

Using point slope form equation

y - y1 = m(x - x1)

Given

Point = ( 6 , 9)

Slope = 3

x1 = 6

y1 = 9

y - 9 = 3(x - 6)

Using a slope intercept form equation

y = mx + c

Open the bracket

y - 9 = 3( x - 6)

y - 9 = 3x - 18

y = 3x - 18 + 9

y = 3x - 9

The equation of the line is

y = 3x - 9

Given y=(2x+3)2, choose the standard form of the given quadratic equation

katrin2010 [14]

$y=(2x+3)^2 = 4x^2 +12x +9$

Taking 4 out from first two terms, we will get

$y=4(x^2+3x)+9$

Now we divide the coefficient of x by 2 and add and subtract the square of the result, we will get

$y=4(x^2+3x+\frac{9}{4}-\frac{9}{4})+9$

Distributing 4

$y=4(x+\frac{3}{2})^2+9-9$

Cancelling 9

$y=4(x+\frac{3}{2})^2$

And that's the required standard form.
