Which equation is the best match for this graph?

• f(x) = -4x + 6

• f(x) = -1/4x + 6

• f(x) = 4x + 6

• f(x) = -1/4x-6

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
