My name is Professor Brownsword and today I will be going over Linear growth! Linear growth is all about rise over run which is essentially slope. The way you find slope is by taking two points on the graph or table and putting the numbers in an equation as y2-Y1 OVER X2-X1. Your x is the independent variable and your y is dependent on the x. Lets put this into some real world context! Say you go candle shopping and every candle is five dollars. The amount of money you spend depends on how many candles you buy… making the amount of candles you buy the X value and the money you spend the Y value. If you get 1 candle you spend 5 dollars which can be represented as 1,5. If you get two candles you spend 10 dollars which can be represented as 2,10. The slope is easy to find if you plug the numbers into the equation. 10-5 over 2-1 is 5. 5 is the slope! Whenever you have a constant relationship between two variables you are able to find linear growth!
rebecca,
