Answer:
y = 90
Step-by-step explanation:
A direct variation is
y = kx where k is a constant
30 = k(-3) from the first set of points
30/-3 = -3k/-3
-10 = k
The equation is y = -10x
Let x = -0
y = -10 * -9
y = 90
To find the y-intercept: replace x with 0
to find the x-intercept: replace y with 0
x-int:
0 = 10x - 32
32 = 10x
x = 3.2
(3.2, 0)
y-int:
y = 10(0) - 32
y = -32
(0, -32)
Let n represent the # of students in the class.
Then 8n candies + 4 candies = 5n candies + 40 candies
Combining like terms: 3n = 36 candies. Solving for n, n = 12 students.
