Determine if lines passing through the points are parallel,perpendicular,or neither line 1: (-2,2)and (2,-4) line 2: (3,6) and (5,3)

You can tell if two lines are parallel, perpendicular, or neither by looking at their slopes and :

Given two points of a line, the slope is defined as the ratio between the y and x variation:

So in this case, we have

Since the two slopes are the same, the two lines are parallel.

Part A: Total cost = 10 + 4s

Part B: Solving for s = 2

10 + 4 * 2 = US$ 18

Correct statement and question:

Write an expression to represent admission to a zoo of $10.00 and the cost of special exhibits s at $4 each. Evaluate your expression when s = 2.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Admission to the zoo = US$ 10

Special exhibit cost (s) = US$ 4

2. Evaluate your expression when s = 2

Total cost = Cost of admission + (s) * Special exhibit cost

Total cost = 10 + (s) * 4

Total cost = 10 + 4s

3. Solving for s = 2

10 + 4s

10 + 4 * 2 = US$ 18
