Two Families went to Rollercoaster World. The Brown Family paid $170 for 3 children and 2 adults. The Peckham Family paid $360 f
or 4 children and 6 adults. If x is the price of children tickets in dollars and y is the price of an adult tickets in dollars. Write a system of equations that models this situation
Every time the x-value increases by 1, the y-value increases by 2. Therefore, the slope of the line must be equal to (rise/y-values over run/x-values). In slope-intercept form , represents the slope of the line, represents the y-intercept, and represents any point the line passes through.
Since represents the slope of the line, the value of
While the question only asks for this value, it's good to note that the equation of the function is (find 7 by substituting any ordered pair in the table with ).
