Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.
We will substitute
and
.

This is the equation of the line with slope -2 that passes through (5,-1).

this seems too easy so I'm probably wrong but thats how I read the question
1/6 percussion
1/3 wood winds = 2/6 (which is twice as many as percussion)
1/2 brass = 3/6 (which is three times as many as percussion)
So percussion = 3
wood winds = 6
brass = 9
all together = 3 + 6 + 9 = 18
We know that 4 cans of coffee cost $1.60. So, if we divide that number by 4, we get

Now we can simply repeat this process again: if we divide both sides by 4, we get
