Answer:
y = -3x + 1
Step-by-step explanation:
The line crosses the y-axis at 1. This is called the y-intercept. This is the number you fill in for c in the form of the equation given.
You can pick any two points on the line to calculate the slope. But you can actually SEE the slope without having to calculate it when you have the graph to look at. See the line crossing the y-axis at 1. Look for another point (that has nice whole number coordinates) there is one DOWN3 and OVER1. If you notice, the next point is also DOWN3 and OVER1.
DOWN3 and OVER1 is the slope -3/1, which is equal to -3.
Fill in -3 in place of the m in the equation.
y = -3x + 1
Done!

Answer:
15 3/4
Yes
Step-by-step explanation:
Given that :
8 boxes = 16 1/4 cups
Required cup of concentrated juice per day = 2 1/4 cups
Total cups that will be required for the entire 7 days :
Number of cups per day * number of days
2 1/4 * 7
= 15 3/4 cups
Since 8 boxes = 16 1/4 ; then 8 boxes will be enough
Answer:
x = 3, -2
Step-by-step explanation:
To help us factor, we can split the middle term up into the sum of the terms -3x and 2x:

From there, we can factor out an x from the first two term and a 2 from the last two to obtain the equation

Factoring out an (x - 3) from each term gives us the equation

At this point, we can divide by either x - 3 or x + 2 to obtain the two equations
and 
Solving both for x gives us the solutions x = 3 and x = -2. We can verify these by substituting them back into the original equation:
