Introduction
Algebra, some of us fear it while some of us embrace it, algebra is not “arithmetic with letters” it is better described as a

One of my favorites are these telephone illustrations, I am constantly searching for the best deal. They provide a good example, since linear functions show a constant rate of change between 2 variables. For example, If a cell phone company charges a start-up fee of $75 and then $.05 for every minute used, the function is y = .05 x + 75.
Or
Back in the days when you actually had to pay for long distance service shopping for the best long distance plan was pretty important. For example a telephone long distance company would cost me $3.00 each month for a $0.03 per minute long distance rate. To calculate the cost where "x" is the number of minutes and "y" is the cost of the long distance usage I can use the linear equation y = 0.03x + 3. So for 60 minutes … y = 0.03x + 3 y = 0.03(60) + 3 y= 0.03 x 60 + 3 y= 4.8

Another one of my favorite examples has to do with cooking a chicken and since I love to cook this was very timely. “The time, in minutes, taken to cook a chicken, C, is linearly related to the weight, in kilograms, of the chicken, k. It takes 40 minutes to cook a 1.4kg chicken and 50 minutes to cook a 1.8kg chicken.
Find the linear equation relating cooking time, C, with the weight of the chicken, k, for a 1.7kg Chicken. This is the same as a line with ordered pairs, (k,C) and two points are given; find the equation for the line. You are looking for C=mk+b, much like
