To find the slope of the linear function, we use the formula:
slope = (change in y)/(change in x)
If we choose any two points from the table, we can calculate the change in y and change in x to find the slope. Let's choose (-3,-6) and (0,-2):
slope = (-2 - (-6))/(0 - (-3)) = 4/3
So the slope of the linear function is 4/3.
To graph the linear function, we can use the point-slope form of the equation, which is:
y - y1 = m(x - x1)
where m is the slope and (x1,y1) is any point on the line. Let's use the point (0,-2):
y - (-2) = (4/3)(x - 0)
Simplifying, we get:
y = (4/3)x - 2
Now we can plot this line on a coordinate plane using the slope as the rise over run. We get:

The dots represent the points from the table, and the line is the graph of the linear function.
The data in the table illustrate a linear function. Find the slope of the linear function and graph the linear function.
x -3 0 3 6
