Answer:
Step-by-step explanation:
The function seems to increase at a constant rate of 3 units. This means that the equation that satisfies these points could be that of a straight line.
We use the first two points to find the slope of the line.
(0, -10)
(1, -7)
(2, -4)
The equation of a line is:
Where m is the slope of the line and b is the cutoff point with the y axis.
To find the slope of a line we use the following equation:
So:
The cut point (b) is found by replacing in the previous equation, any of the three points provided and clearing b.
Now we can write the equation of the line sought.
You can verify that the three points provided belong to this equation.
