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 […]

Equation of a line: The derivation of y = mx + b

We have discussed in context the origin (click here and here) of the linear equation , where and are real numbers.  We have also talked about the slope of a line and many of its properties. In this post, we will discuss the generalization of the equation of a line in the coordinate plane based on its slope and […]
