The x and y-intercept are given as:
x-intercept (x,y) : (30, 0)
y-intercept (x,y) : (0, 50)
Let the general admission ticket be x
Let the student ID ticket be y
If concert tickets cost $15 for general admission, but only $9 with a student ID, this can be expressed as 15x + 9y
If the total sales is $450, the equation becomes 15x + 9y = 450
The x-intercept occurs at y = 0
15x + 9(0) = 450
15x = 450
x = 30
The x-intercept is at (30, 0)
The y-intercept occurs at x = 0
15(0) + 9y = 450
9y = 450
y = 450/9
The y-intercept is at (0, 50)
