Given data:

The first set of equations are x+y=4, and x=6.

The second set of equations are 3x-y=12 and y=-6.

The point of intersection of first set of te equations is,

6+y=4

y=-2

The first point is (6, -2).

The point of intersection of second set of te equations is,

3x-(-6)=12

3x+6=12

3x=6

x=2

The second point is (2, -6).

The equation of the line passing through (6, -2) and (2, -6) is,

\begin{gathered} y-(-2)=\frac{-6-(-2)}{2-6}(x-6) \\ y+2=\frac{-6+2}{-4}(x-6) \\ y+2=x-6 \\ y=x-8 \end{gathered}

Thus, the required equation of the line is y=x-8.

You can set this up as an algebraic equation using the ratio:

\frac{1}{2} = \frac{x}{x+1250}
where x = number of skiers

Cross multiply:
x + 1250 = 2x

Solve for x:
-x = -1250
x=1250

To find the number of snowboarders, add 1250.
1250 + 1250 = 2500

1250 skiers and 2500 snowboarders bought season passes.
