**Linear Equations**which are strait lines and only cross the

**y-axis**and

**x-axis**once. Whose general form is

**Ax+By+C=O.**Which you can use to find the

**y-intercept**(o,y) and

**x-intercept**(x,0). The general form of the linear equation can be transformed to different forms:

**slope-Intercept form-y=mx+b**where

**m**is the

**slope**and

**b**is the

**y-intercept**of the equation and are constant, and

**point-slope form:**

**y - y 1 = m(x - x 1 )**. You use the

**slope-intercept form**to plug it in your graphing calculator and graph it.

In this project, I chose to find a linear model for American's personal income and find out the values in certain years. I used the slope-intercept form to write out the equation and below is my work and graph of my equation.
