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.

y = 3x+1 Solve for out Y when input X is at 10

• 25

• 31

• 14

• 41

4x + y= Is this equation Linear

• Yes

• No

Change equation to a linear equation 4x +y = 10

• +y=4x-10

• y=4x-10

• y= -4x +10

• y= -4x -10

Max is running a bakery and needs flour to bake his cakes. For every cake he needs 2 cups of flour. What equation would represent this situation

• 2x=Y + 1

• y= 2x+1

• 2x + y = 1

• y= 2x
