Apologies for the confusion. Let's find out if the lines intersect or not.
First, let's find the slope of the line through (3, 7) and (-2, -5):
slope = (change in y) / (change in x)
= (-5 - 7) / (-2 - 3)
= -12 / -5
= 12/5
Now, let's find the slope of the line through (4, 8) and (10, -2):
slope = (change in y) / (change in x)
= (-2 - 8) / (10 - 4)
= -10 / 6
= -5/3
Since the slopes of the two lines are different (12/5 and -5/3), the lines are not parallel.
So, the correct answer is: Yes, these lines are not parallel.

To determine which option is best in each scenario, we'll calculate the total cost for each option and compare them.
Scenario 1: You plan to attend 3 times this summer.
Option 1: Pay per visit
Total cost = 3 * $28 = $84
Option 2: Buy a membership
Total cost = $90 (membership fee) + 3 * $15 (visits) = $135
In this scenario, the Pay per visit option is more cost-effective.
Scenario 2: You think you will visit approximately 8 times this summer.
Option 1: Pay per visit
Total cost = 8 * $28 = $224
Option 2: Buy a membership
Total cost = $90 (membership fee) + 8 * $15 (visits) = $210
In this scenario, the Buy a membership option is more cost-effective.
Scenario 3: You have budgeted $150 for visiting the park this summer.
Option 1: Pay per visit
Maximum number of visits = $150 / $28 = 5.36 (rounded down to 5 visits)
Total cost = 5 * $28 = $140
Option 2: Buy a membership
Total cost = $90 (membership fee) + 5 * $15 (visits) = $165
In this scenario, the Pay per visit option is more cost-effective.
Scenario 4: Break-even point where both options cost about the same.
Let's assume the number of visits as x.
Option 1: Pay per visit
Total cost = x * $28 = $28x
Option 2: Buy a membership
Total cost = $90 (membership fee) + x * $15 (visits) = $90 + $15x
Setting the costs equal to each other:
$28x = $90 + $15x
$13x = $90
x = 6.92 (rounded up to 7 visits)
Approximately, the break-even point is around 7 visits.
To summarize:
1. For 3 visits, the Pay per visit option is best.
2. For around 8 visits, the Buy a membership option is best.
3. With a budget of $150, the Pay per visit option is best.
4. The break-even point is around 7 visits.

As an AI language model, I don't have personal preferences or opinions. However, I can provide some information about the different methods of solving a system of linear equations.
There are three common methods for solving a system of linear equations:
1. Graphing method: This involves graphing the equations on the coordinate plane and finding the point of intersection, which represents the solution.
2. Substitution method: This involves solving one equation for one variable and substituting that expression into the other equation. By doing this, you can solve for the other variable and find the solution.
3. Elimination method: This involves adding or subtracting the equations in a way that eliminates one variable when combined. After eliminating a variable, you can solve for the remaining variable and find the solution.
The choice of method depends on personal preference, the complexity of the equations, and the specific situation. Some people may find graphing easier when dealing with basic linear equations, as it allows for a visual representation of the solution. On the other hand, the substitution method or elimination method may be preferred when dealing with more complex equations or systems with numerous variables.
Each method has its advantages and disadvantages, and the preference for one over the others will vary from person to person. Some may find the graphing method easier to conceptualize, while others may prefer the algebraic manipulation involved in the substitution or elimination methods. It is recommended to familiarize oneself with all three methods and choose the one that feels the most comfortable and efficient for a given problem.
