## The effect of adding b to the linear function y = ax + b

In the previous post, we have learned about the effects of a in the linear function with equation y = ax. In this post, we learn about the effects of adding b to that equation. That is, we want to learn the effects of b in the linear function with equation y = ax + […]

## Increasing and Decreasing a in the linear function y = ax

In the previous post, we have learned the effect of the sign of a in the linear function . In this post, we learn the effect of increasing and decreasing the value of a. Since we have already learned that if , the graph is a horizontal line, we will discuss 2 cases in this […]
