In chapter P the book talks about 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.
