In order to answer this problem, let us assume that x is the number of hours (the independent variable) and y is the score obtained (the dependent variable). The value 65.8 is the y-intercept which means that we will get y = 65.8 if x is equal to zero. This means that 65.8 is the score that one can get if he does not study at all.
You would add 5 and 17 and that would equal 22 Now it would be 22=J-14 Then add 14 on both sides so it cancels out 22 plus 14 is 36 So J would equal 36
