1. The problem asks to determine if each statement about coordinates and axes is true or false. 2. Statement 1: "In the ordered pair (3, 5), the number 5 is the y-coordinate." - By definition, an ordered pair is written as $(x, y)$ where $x$ is the x-coordinate and $y$ is the y-coordinate. - Here, $(3, 5)$ means $x=3$ and $y=5$. - Therefore, the number 5 is indeed the y-coordinate. - This statement is **True**. 3. Statement 2: "The origin has coordinates (0, 0)." - The origin is the point where the x-axis and y-axis intersect. - By definition, the origin is at $(0, 0)$. - This statement is **True**. 4. Statement 3: "The horizontal axis in a coordinate plane is the y-axis." - The horizontal axis is called the x-axis. - The vertical axis is called the y-axis. - Therefore, this statement is **False**. Final answers: - Statement 1: True - Statement 2: True - Statement 3: False
