When you graph a line using slope-intercept form, you plot the  ___________ first and then the ___________.

• origin; slope 
• slope; y-intercept
• y-intercept; x-intercept
• y-intercept; slope

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.
