Answer:

20 games.

Step-by-step explanation:

Given:

Meredith is playing games at an arcade to earn tickets that she can exchange for a prize.

She has 255 tickets from a previous visit.

She earns 6 tickets for each game she plays.

Meredith needs 375 tickets to exchange for the prize she wants.

Question asked:

How many games does Meredith need to play?

Solution:

Total tickets needed to exchange for the prize = 375

Meredith already have = 255 tickets

More tickets needed = 375 - 255 = 120 tickets

By unitary method:

She earns 6 tickets by playing = 1 game

She earns 1 ticket by playing = $\frac{1}{6}$ game

She earns 120 tickets by playing = $\frac{1}{6}\times120=\frac{120}{6} =20\ games$

Therefore, she needs to play 20 games to earn 120 more tickets.

Answer:

Step-by-step explanation:

Correct me if I'm wrong but...

1st you would choose two ordered pairs. Like, for instance, in the graph I only see (-4,-4) & (6,8) as whole points. Then, you would use the formula: Y2 - Y1*line*X2-X1. Then, if you need to simplify, you can simplify. After that, put it in Point-Slope Form: Y-Y1=m(x-X1) and there is your answer.
