Chapter 5: Problem 5
For each of the following, graph the given points. $$ (0,3) $$
Short Answer
Expert verified
Plot (0,3) by moving 3 units up from the origin.
Step by step solution
01
- Understand the Coordinate System
The coordinate system consists of two axes: the horizontal axis (x-axis) and the vertical axis (y-axis). Points are given in the format (x, y), where x is the position on the horizontal axis and y is the position on the vertical axis.
02
- Identify the Coordinates
Identify the x and y coordinates from the given point (0, 3). Here, x = 0 and y = 3.
03
- Plot the x-coordinate
Move along the x-axis to the x-coordinate value. In this case, the x-coordinate is 0, so stay at the origin (where the x-axis and y-axis intersect).
04
- Plot the y-coordinate
From the x-axis (the origin point here), move vertically to the y-coordinate value, which is 3. Count 3 units up along the y-axis.
05
- Mark the Point
Mark the point where the x and y coordinates intersect. This is the point (0, 3) on the graph.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Understanding the Coordinate System
A coordinate system helps us locate points on a plane using two number lines. These number lines are known as axes. The horizontal line is called the x-axis, and the vertical line is the y-axis. Both axes cross at a point named the origin, marked as (0, 0). Points on this system are given as pairs (x, y), where:
- x represents the position along the x-axis.
- y represents the position along the y-axis.
The X-Axis
The x-axis runs horizontally across the coordinate plane. It is the baseline from which we measure horizontal distances.
- Positive x-values are located to the right of the origin.
- Negative x-values are located to the left of the origin.
The Y-Axis
The y-axis runs vertically on the coordinate plane. It is used to measure vertical distances from the origin.
- Positive y-values are above the origin.
- Negative y-values are below the origin.
Plotting Points
When plotting points, we use both the x and y coordinates to find the exact spot on the coordinate plane. Here’s a step-by-step guide:
- Identify the x and y coordinates from the point. For example, with the point (0, 3), x = 0 and y = 3.
- Start at the origin, where the x-axis and y-axis meet (0, 0).
- Move horizontally to the x-coordinate. In this case, stay at 0 on the x-axis.
- From this point on the x-axis, move vertically to the y-coordinate. Here, move 3 units up.
- Mark this point on the graph. You have now plotted the point (0, 3).
