*the function drawn by Jamal is the attachment below
Answer:
A) It is linear because it has a constant rate of change.
Explanation:
When you plot all the coordinates of a linear function on a graph, the line that passes through all the points plotted is typically a straight line. There would be absence of any curve or bends. All you'd have is a straight line.
Consequent on this, a straight line indicates that the rate of change remains the same along the line slope.
If you pick any two points on the line and calculate the rate of change, it would give you the same rate of change you'd get when you calculate the rate of change of another two points on the line.
A straight line indicates a constant rate of change. Therefore, the function drawn by Jamal is a linear function because it has a constant rate of change.
