The formula is y2-y1 over x2-x1. If you plug in you points that would be 18-(-9) over -10-4. Subtract and that’ll be your answer. Hope this helps!

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.
