  • It is linear as the equation performs ax+by +c
  • y = 90.2x - 177670
  • number of student to enroll 2011 is 3722

Step-by-step explanation:

  • Linear is a straight line.
  • Quadratic is a square which generates parabola.
  • Quadratic formula is (ax)^2 + bx + c = 0.
  • Linear formula is ax+bx + c = 0
  • To  forecast time series data modelling can be used.
  • To form a linear equation y = mx + c.
  • After finding x is the required value , m is the intercept and C constant.
  • X axis have years and Y axis has the value.
  • to find number of students x is 90.2 * 2011 - 177670.
  • The result comes to 3722.
  • In Data analysis predictive modeling is the second phase.
  • It is important because it helps in associating to variables.
