Answer:

Options: 1, 4 & 6

Step-by-step explanation:

Yes:

1. $-1(x-1)^{2} +9=-1(x^{2} -2x+1)+9=-x^{2} +2x-1+9=-x^{2} +2x+8$

4. $-x^{2} +2x+8$

6. $(x+2)(4-x)=2x-x^{2} +8=-x^{2} +2x+8$

No:

2. $-(x-9)^{2} +1=-(x^{2} -18x+81)+1=-x^{2} +18x+81+1=-x^{2} +18x+82$

3. $x^{2} +2x-8$

5. $(x+2)(x-4)=x^{2} -2x-8$

Write an equation for the line graphed below: y=??

Zepler [3.9K]

Answer: y=-2x-1

Step-by-step explanation:

First let's find the slope by using the formula $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$\frac{-3--1}{1-0} \\\frac{-2}{1} \\-2$

The equation for slope intercept form is y=mx+b where m is the slope and b is the y-intercept

The y-intercept is -1 giving us the equation

y=-2x-1
