1) This question is asking for the linear equation of the data in the table.
Remember a linear equation in slope-intercept form for this problem is something like a = cm + b, where c = the slope of the equation, b = the y intercept,
and m and a are your variables (and values in the table).
This might be confusing if you haven't learned it! Don't worry, all you need to know is the equation and just plug in values to find b (since that's the number that different in all your answer choices).
2) All your answer options have the same slope, c = -4000. All you want to find is the value of b, the y-intercept.
This value you can find by plugging in a set of values from the table into your equation, knowing c = -4000. Let's plug in the first row of values: m = 1, a = 35000.
a = cm + b
a = -4000m + b
35000 = (-4000)(1) + b
35000 = -4000 + b
39000 = b
3) That means b = 39000. Put b = 39000 and c = -4000 together into your equation a = cm + b to get your final equation:
a = cm + b
a = -4000m + 39000
That is answer choice B.
------
Answer: B) -4000m + 39000
Answer:
I have a great love for books. I always try to save money to buy books. I understand the value of books, for me, the investment I put in books is worth it. Now I have enough savings to buy the books I like. In the future, I hope to be able to use my precious books as a tool to help young people in particular and society in general. Therefore, I intend to use that "book" investment to build a library for poor children who want to read books, they can read books for free. Although I won't bring in a large sum of money, it makes me happy.
2x2-6x= - 8
Simplify both sides
2x(2) = 4x
Combine like terms
4x + (-6x) =-8
-2x = -8
Divide each side by -2
X = 4
