| **From the given linear functions, indicate the one whose graph increases 1) y = -x + 5; 2) y = 7; 3) y = -3x; 4) y = 2x + 8? Write down the function number in your response.**

A linear function of the form y = kx + b increases on the entire set of numbers if k> 0 and decreases for k <0. Then:

1) k = -1 <0 the function decreases;

2) k = 0 is not increasing;

3) k = -3 <0 is a decreasing function;

4) k = 2> 0 is an increasing function.

Answer: 4).
