Math Problem Statement
Which function represents the relationship between the x and y values listed in the table?
Solution
To solve this problem, we need to find the linear function that fits the points given in the table.
The table provides the following points:
Step 1: Calculate the slope of the line (m).
The formula for the slope between two points and is:
Let's use the points and first:
The slope is .
Step 2: Check the slope with other points.
Now, let's check the slope using the points and :
The slope is consistent, so the slope of the line is indeed .
Step 3: Use the point-slope form to find the equation.
We can use the point-slope form of the equation:
Using the point and the slope , we plug in the values:
Distribute the :
Now solve for :
Step 4: Check the answer.
The correct equation is:
So the correct
