Finding Equations of Additive or Multiplicative

In graphs of multiplicative relationships, the graph always starts at the origin (0,0).

• True

• False

In graphs of additive relationships, the graph always starts at the origin (0,0).

• True

• False

What is the correct equation for a multiplicative relationship?

• y = x + a
• x = y + a 
• y = ax
• a/x = m

What is the correct equation for an additive relationship?

• y = x+a
• x = y+a
• y = ax
• a/x = m

Is the picture showing an additive or a multiplicative relationship?
