Final answer:
To write an equation in slope-intercept form for the total cost of any number of tickets at 7 tickets for $5, the equation is y = (-5/7)x + 5. For the total cost of a wristband for all you can ride, the equation is y = 25.
Step-by-step explanation:
To write an equation in slope-intercept form for the total cost of any number of tickets at 7 tickets for $5, we can use the formula y = mx + b, where y represents the total cost, m represents the slope, x represents the number of tickets, and b represents the y-intercept.
Since 7 tickets cost $5, we have a slope of -5/7 and a y-intercept of $5.
Therefore, the equation in slope-intercept form is y = (-5/7)x + 5.
For the total cost of a wristband for all you can ride, which costs $25, the equation in slope-intercept form would be y = 0x + 25, or simply y = 25.
