Answer:
y=x-9
Step-by-step explanation:
Answer:
Y would just equal 6. It says so. Imagine that line where the line is just at y=-6. And imagine all of the points on that line with 4, 5, and -2/3 as the x.
Step-by-step explanation:
I cant see :( Try another picture even though this might be too late I'm sorry.
<span>y = 3x² + 18x
factor out the leading coefficient
y = 3(x²+6x)
Complete the square
coefficient of the x term: 6
divide it in half: 3
square it: 3²
use 3² to complete the square:
y = 3(x²+6x + 3²) - 3·3²
= 3(x+3)² - 3·3²
= 3(x+3)² - 27
vertex (-3, -27)</span>
