Find the slope between the two points.
(3, 7) and (-4, 2)

• ⁷/₅
• ⁵/₇
• ²/₃
• 2

• No Solution

• Infinite Solutions

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.
