Question

your friend is graphing the point (2, 5). her first step is to start at the origin and go up 2 units. is her method correct? it is not correct because the first number tells you how far to go right or left, not up or down. it is correct because you must start counting from the bottom left corner in this type of graph. it is correct because the first number in the pair tells how far to go in a vertical direction, which is up. it is not correct because you should always start with the second number.

Explanation:

Step1: Recall coordinate - point rules

In an ordered pair $(x,y)$ in a Cartesian coordinate system, $x$ represents the horizontal displacement and $y$ represents the vertical displacement. For the point $(2,5)$, $x = 2$ and $y=5$.

Step2: Analyze the first - step action

To graph the point $(2,5)$, starting from the origin $(0,0)$, the first step should be to move 2 units to the right (because $x = 2$ and positive $x$ values mean moving to the right along the x - axis), not 2 units up.

Answer:

It is not correct because the first number tells you how far to go right or left, not up or down.
