Given:
64 total students
x = drama club students
y = yearbook club students
x = y + 10
y = 64 - x
y = 64 - x
y = 64 - (y + 10)
y = 64 - y - 10
y + y = 64 - 10
2y = 54
2y/2 = 54/2
y = 27
x = y + 10
x = 27 + 10
x = 37
To check:
x + y = 64
37 + 27 = 64
64 = 64
3). y = -1/3x + 5
4). y = -1x +5
Slope intercept form: y = mx + b
m = slope
b = y intercept
C is the answer.
The other ones do not make as much sense i am not completely sure.
