Diana is a homebound teacher who charges $45 per hour plus an additional flat fee of $20 for travel. the equation that represents this situation is y = 45x + 20, where x represents the number of hours of classes and y represents the total cost. another teacher, paula, creates a graph comparing the total amount diana charges for a session and the total amount she charges for a session. paula finds her graph is shifted below diana's line, and her line is also steeper than diana's line. paula charges less per hour and has a lower travel fee. paula charges more per hour but has a lower travel fee. paula charges less per hour but has a higher travel fee. paula charges more per hour and has a higher travel fee. select the correct answer and i will give the brainlest and ten points

Paula charges more per hour but has a lower travel fee.

Step-by-step explanation:

The equation that represents Diana's situation is

x represents the number of hours of classes

y represents the total cost.

Paula finds her graph is shifted below Diana's line, and her line is also steeper than Diana's line.

So, the answer is : Paula charges more per hour that makes the graph more steeper, and has a lower travel fee that results in graph shifting below Diana's line.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
