What is the slope and y-intercept for the ghraph of y+9x=-6

Y intercept:

Y=-6-9(0)
=-6

(0,-6)

I’m assuming the slope is the gradient if that’s the case then it would be -9 since
Y=mx+c
m is the gradient and in this case it’s -9

Answer:

slope: -9 y-intercept: -6

Step-by-step explanation:

the equation y = mx + b is the equation to find the slope and y intercept where m is the slope and b is the y intercept so change your equation to get y on one side so you would subtract 9x from both sides so it would then be y = -9x -6 where -9 is the slope and -6 is the y intercept

Nathan and his brother Zach love to play video games. Right

Monica [59]

Answer:

$N=2Z-11$

$\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}$

Step-by-step explanation:

Nathan's score is 11 less than 2 times Zac's score.

Let Z points be Zac's score and N points be Natan's score. then

2 times Zac's score = 2Z

11 less than 2 times Zac's score = 2Z -11

So, N = 2Z - 11

1. If Z=6, then $N=2\cdot 6-11=12-11=1$

2. If Z=7, then $N=2\cdot 7-11=14-11=3$

3. If Z=8, then $N=2\cdot 8-11=16-11=5$

4. If Z=9, then $N=2\cdot 9-11=18-11=7$

Thus, four other possibilities are

$\begin{array}{cc}\text{Zac's score}&\text{Natan's score}\\ 6&1\\7&3\\8&5\\9&7\end{array}$

Albertson's found that the demand for Coke products varies inversely as the price of the product. When the price of a Coke produ

romanna [79]

Answer:

859

Step-by-step explanation:

The demand for Coke products varies inversely as the price of Cole products.

Mathematically:

D α 1/p

Where D = demand, p = price of coke product

D = k/p

Where k = constant of proportionality.

Let us find k.

k = D * p

When Demand, D, is 1250, price, p, is $2.75:

=> k = 1250 * 2.75

k = $3437.5

Now, when price, p, is $4, the demand will be:

D = 3437.5/4

D = 859.375 = 859 (rounding to whole number)

The demand for the product is 859 when the price is $4.

Find the slope of the line. <br><br> A. 1/3<br> B. - 1/3<br> C. 3<br> D. -3

BARSIC [14]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (0, -2) and (6, 0).

Substitute:

$m=\dfrac{0-(-2)}{6-0}=\dfrac{2}{6}=\dfrac{1}{3}$

<h3>Answer: A. 1/3</h3>
