Answer:
The function is .
The slope is .
The y-intercept is .
Step-by-step explanation:
Our aim is to calculate the values <em>m</em> (slope) and <em>b</em> (y-intercept) in the equation of a line :
We have the following data:
To find the line of best fit for the points given, you must:
Step 1: Find and
as it was done in the table below.
Step 2: Find the sum of every column:
Step 3: Use the following equations to find <em>b</em> and <em>m</em>:
Step 4: Assemble the equation of a line
The graph of the regression line is:
Step-by-step explanation:
First we need to isolate the y, by dividing -4 on both sides. This will give you y = 1/4x - 5.
Now you can properly graph the equation:
Since -5 is the y-intercept (the point in which the line intercepts the y-axis), we will place our first point at (0,-5) on the graph.
In order to find the next point, we will use the slope of the line and do rise/run. So we will go upwards 1 unit and to the right 4 units.
