Given Equation:

  Equation:1

or      Equation:2

Using Substitution method, put the value of 'x' in equation:1

Subtracting '12' both sides:

Putting value of 'y' in equation:2

So, the values are:  

line or a linear equation graph

step-by-step explanation:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
