Company 1 because the cost of 500 text messages is $15.
Company 1 because the cost of 500 text messages is $20.
Company 2 because the cost of 500 text messages is $25.

y = 2x. y is double x.
y = 3x. y is triple x.
y = 2x + 1. y is twice x plus 1.
y = 2x - 1. y is twice x minus 1.

Henry is starting a t-shirt printing business and plans on selling each shirt for $30, with his cost being $8 per shirt. The equipment will cost $1200. Henry orders 600 shirts and determines that the profit for his new business is modeled by the function P = 22x - 1200. What is the domain of this function in this context?

No, they are not equal. The slope is never the same along the entire line.
Yes, they are equal. Slopes of lines are always equal along the entire line.
No, they are not equal. Sometimes the slope is the same along the entire line, but not in this case.
Yes, they are equal. This is a coincidence. Slopes of lines are not always the same along the entire line.
