To Graph: The equation
a.
Explanation of Solution
Given information:
The given equation
Calculation:
To find the x-intercept, let
(Replace y by 0)
(Simplify)
(Divide by 15 on both sides)
(Simplify)
The x-intercept is 12. This means that the graph intersects the x-axis at.
To find the y-intercept, let
(Replace x by 0)
(Simplify)
(Divide by 30 on both sides)
(Simplify)
The y-intercept is 6. This means the graph intersects the y-axis at.
Plot these two points and then draw a line through them.

Answer to Problem 12CYU
The required answer is: The x-intercept 12 means that 12 children can attend the rodeo if there are 0 adults.
Similarly, the y-intercept means that 6 adults can attend the rodeo if there are 0 children.
Explanation of Solution
Given information:
The equation which represents the number of children x and adults y who can attend the rodeo for $180.
Calculation:
The x-intercept 12 means that 12 children can attend the rodeo if there are 0 adults.
Similarly, the y-intercept means that 6 adults can attend the rodeo if there are 0 children.
