Frequently Asked Questions

What is a linear function?

A linear function is a function of the form y = kx + b, where k and b are numbers and k ≠ 0. Its graph is a straight line.

How do you plot the graph of a linear function?

Two points are enough: substitute two values of x, find the corresponding y values, mark the points on the coordinate plane, and draw a straight line through them.

What does the slope k mean?

If k > 0, the function is increasing. If k < 0, it is decreasing. The larger |k| is, the steeper the line.
