Prediction with a line
                         When writing an equation given two points, you first
                         have to plug your points into the slope formula.
                         (          )
                         After you get those numbers you have to plug them
                         into the point slope formula
                         (           )
                         Now you have the form of y=mx+b, plug in your
                         prediction for x and solve.

       My first year was 1860
      and I predicted what the
     population was going to be
     in 2061. 2061 is 201 years
    away from 1860, I plugged in
       201 for x and found my
    population for the year 2061.

Prediction with a line
                         When writing an equation, you first have to find the
                         x and y values for the three points on your curve.
                         After you get the x and y values you have to plug
                         each of them into the formula,Y=ax^2+bx+c
                         When you get your two equations, use the
                         elimination method to solve for either a or b.
                         When you have the value for either a or b, plug it
                         into the original equation and solve for the missing
                         variable.

Prediction with a line
                         When writing an equation you have to plug your y
                         value in for y and your x value in for x in the
                         equation,Y=ab^x.
                         Then solve the equation for either variable (a or b).
                         Plug the value of the variable you solved for into the
                         original equation and solve for the missing variable.
                         Now that you have all the numbers for the missing
                         variables, solve the equation to find the prediction
                         for the year 2016.
