• 
• 

What is slope intercept form?

• y = kx
• y - y1 = m (x - x1)
• y = mx + b
• Ax + By = C

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.
