1. Problem Description
We are given a table of x and y values that represent a linear function. We need to determine the equation of this linear function in slope-intercept form, which is , where is the slope and is the y-intercept.
2. Solution Steps
First, we need to determine the slope . We can use any two points from the table to calculate the slope. Let's use the points and . The formula for the slope is:
Plugging in the coordinates of the points, we get:
So, the slope .
Now, we need to find the y-intercept . We can use the slope-intercept form and substitute the slope and one of the points from the table to solve for . Let's use the point .
Therefore, the y-intercept is .
The y-intercept as an ordered pair is .
Now that we have the slope and the y-intercept , we can write the equation of the linear function in slope-intercept form:
3. Final Answer
Slope: -11
Vertical Intercept (as an ordered pair): (0, -2)
Equation for the Linear Function:
