Taryn conducted a science experiment on saturation. she added sugar to a sugar-water solution at different intervals. the graph shows how much sugar was in the solution at different times.
complete the equation that represents taryn’s situation.
y = x +

     The function graph is a straight, so the function is the first-degree. The first-degree polynomial funciton of can be generalized as follows:

 
  
     To find the unkwnons, we need to extract two chart points. I chose these :(0;1), (14;8).
  
     The slope (a) is give by:
 


     The linear correlation coefficient of the equation (b) is obtained when the variable is zero, therefore:


 
     Throught it we have sought the equations is given by:
