Kim bought $100 worth of stock and gained $25 per year. ari bought $400 worth of stock and lost $35 per year. use x for time and y for stock value. graph the equations that represent each situation. the first one is done for you.

1. Kim's case:
We know for our problem that she will gain $25 each year, so if  represents the number of years, she will gain , where  is the number of years. We also know that her initial investment is $100. If we let  represent the stock value after  years, we can relate the quantities with the following equation:


We can conclude that the first image is the graph of the equation that represent Kim's situation.

2. Ari's case:
In this case, he is losing $35 per year. Let  represent the number of years. Since we know that losses are represented with a minus sign, he will lose -35x per year. Now, we know for our problem that her initial investment is $400. If we let  represent the stock value after  years, we can relate the quantities with the following equation:


We can conclude that the second image is the graph of the equation that represent Ari's situation.

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
