Answer:
hello :
note :
the linear function of x have equation : y = ax + b
correct answer is : A) and C) and E)
A) : 3y = 2x -15
y = (2/3)x -15/3
y = ( 2/3)x -5 ..... when : a = 2/3 and b = -5
B) : 5(x+y)=-25
x + y = - 5
y = - x -5 ...... when : a = -1 and b = -5
C) y = 1
y = 0x +1 .....when : a = 0 and b = 1
