Answer:
b. 3y=-x+9
Step-by-step explanation:
substitute the given equation:
f(x) is the equivalent of y
m is the value of x
b is the constant number
Answer:
Letter C. f(x) = -1/3x+3
Step-by-step explanation:
SLOPE INTERCEPT FORM: y = mx+b
Solution:
x+3y = 9
3y = -x+9
3y = -x+9
3 3
y = _ 1 x + 3
3
f(x) = -1/3x+3
