Write a linear equation in slope intercept form of a line with a slope of -3 and y intercept of 0

• y=-3

• y=3x

• y=-3x

• x=-3

Write a linear equation in slope intercept form of a line with a slope of 12 and y intercept of 10

• y=12x-10

• y=10x+12

• y=12x+10

• x=10x-12

Is this mapping a function or not a function? 

• Function
• Not a Function 

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.

What is the domain?

• {-4, -1, 0, 2, 7}
• {-5, -4, -1, 0, 1, 2, 4, 7}
• {-5, 0, 1, 2, 4}
• {5}

What is the Domain?

• {-3, -1, 1, 3, 5, 7, 9}
• {-3, -2, -1, 0, 1, 2, 3}
• -3 ≤ x ≤ 3
• -3 ≤ x ≤ 9
