Introduction to solving by graphing

If you were to plot the point (4, -12) what would be the correct method?

• Up 4, left 12
• Right 4, up 12
• Down 4, left 12
• Right 4, down 12

HOW is a coordinate pair ordered?

• (big number, small number)

• (small number, big number)

• (y, x)

• (x, y)

Write the equation in solve-intercept form (solve for y):
3y = 2x + 9

• y = 2/3x + 3
• y = 2x + 3
• y = 2x + 6
• y = 3/2x + 6

The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Which equations represents the system that could be used? 

• 1s + 3c = 38
  2s + 3c = 52
• 3s + 1c = 38
  3s + 2c = 52
• s + c = 38
  s + c = 52
• 3s + 3c = 38
  1s + 2c = 52
