Question

which point has coordinates (1, -4 1/2)?

Explanation:

Step1: Understand coordinate system

In a 2 - D coordinate system, the first number in $(x,y)$ is the x - coordinate and the second is the y - coordinate. Here $x = 1$ and $y=-4\frac{1}{2}$.

Step2: Locate x - coordinate

Find the vertical line corresponding to $x = 1$ on the x - axis.

Step3: Locate y - coordinate

Find the horizontal line corresponding to $y=-4\frac{1}{2}$ on the y - axis. The intersection of the vertical line $x = 1$ and the horizontal line $y=-4\frac{1}{2}$ gives the point. Looking at the graph, the point C is at $x = 1$ and $y=-4\frac{1}{2}$.

Answer:

C
