Answer:

\displaystyle y = -3x + 9

Step-by-step explanation:

First, find the <em>rate of change</em> of the line:

\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}

_______________________________________________

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}

I am joyous to assist you at any time.

Marcia bought a bag of red white and blue balloons for the party there were 49 balloons in the bag if there are twice as many re
DedPeter [7]

Answer:

Red color= 28 balloon

Blue color= 14 balloon

White color= 7 balloon

Step-by-step explanation:

Given: There are 49 balloons

As given, there are 2 red balloon equal to the number of blue balloon

∴ 2 red= blue\ balloon

Again given, there are 1/2 white balloon equal to the number of blue balloon.

∴ \frac{1}{2} \ white= blue\ balloon

As above equation, we can understand that:

2\ red= \frac{1}{2} \ white\ balloon

multiplying both side by 2

⇒ 4\ red= white\ balloon

which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.

∴ Total combination of all color of balloon= 2+4+1= 7

Now, checking how many number of times combination can we have in 49 balloon.

\frac{49}{7}= 7 \ times

Next, finding number of balloon in each color.

Red color= 4\times 7= 28\ balloon

Blues color= 2\times 7= 14\ balloon

White color= 1\times 7= 7\ balloon
