Y - y1 = m(x-x1)
y - 2 = 3(x-6)
y - 2 = 3x - 18
y = 3x -18 +2
y = 3x -16
Answer:
John need to get 293 in his next game to bring his average up to 183.
Step-by-step explanation:
John starts with N games played and averaging 177 points per game.
In game N+1, John scored 199 points.

So, John has now played (N+1) = 22 games.
We need to know what score John needs in game 23 to bring his average to 183.

Do the multiplication and division first.
21 / 7 = 3
20 * 100 * 2 = 4000.

3 + 4000 - 3 = 4000
One hundred twenty three thousand seven hundred eighty nine
