Okie help help math math math
liraira [26]

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.

PLEASE HELP WITH MIDDLE SCHOOL MATH 1 Q THATS MULTIPLE CHOICE I NEED HELP PLEASE FOR BRAINLIEST*(08.06 MC)
Bess [88]
All you have to do is try out both of the equations with each of the different choices.

200 = 45 (3) + 20
200 = 135 + 20
200 = 155

200 = 35 (3) + 60
200 = 105 + 60
200 = 165
So, this one does not work.
--------------------------------------------
180 = 45 (3) + 20
180 = 135 + 20
180 = 155

180 = 35 (3) + 60
180 = 105 + 60
180 = 165
So, this one does not work.
----------------------------------------------
200 = 45 (4) + 20
200 = 180 + 20
200 = 200

200 = 35 (4) + 60
200 = 140 + 60
200 = 200
So this one works.

The answer would be C.

I hope this helps and I'm sorry it took so long!
