Step-by-step explanation:
Kayden:Kayah:Kayla:Michelle
2:3:4:3
2k+3k+4k+3k=36
12k=36
k=36:12
k= 3
Kayden- 2•3=6
Kayah- 3•3=9
Kayla= 4•3=12
Michelle= 3•3=9
Answer:
D.
Step-by-step explanation:

Find the slope first by using rise/run


We need to find the y-intercept. Substituting one of given ordered pairs. I will use (-2,-1).
Substitute x = -2 and y = -1 in the equation.

Thus the y-intercept is 4/3.
From y = mx+b, the equation is.

Answer:
x+3y=-9
Step-by-step explanation:
-2(x+3y)=18
x+3y=18/-2
x+3y=-9
