Answer:

See below

Explanation:

Part A

Standard form is Ax + By = C

x - price of adult tickets, y - price of child tickets, the equation in the standard form is:

  • 15x + 9y = 90 ⇒ 5x + 3y = 30

Part B

y-intercept is obtained when x = 0

  • 15*0 + 9y = 90
  • 9y = 90
  • y = 10

It represents the amount of child tickets if no adult tickets sold

x-intercept is obtained when y = 0

  • 15x + y*0 = 90
  • 15x = 90
  • x = 6

It represents the amount of adult tickets if no child tickets sold

Part C

Converting the equation into slope-intercept form of y = mx + b

  • 5x + 3y = 30
  • 3y = -5x + 30
  • y = -5/3x + 30/3
  • y = -5/3x + 10

Part D

  • The slope is -5/3. It represents the negative ratio of ticket prices
