Coordinates and Line Graphs: Coordinates, Line Graphs and Linear Graphs
A short read for Class 8 before you play. These notes cover Introduction to Graphs: Coordinates and Line Graphs.
📍 Coordinates and axes
Two number lines, the horizontal x-axis and the vertical y-axis, meet at the origin (0, 0). A point is written as (x, y). To plot (3, 2) go 3 units right and 2 units up.
🧭 Quadrants
The axes split the plane into four quadrants. The signs of x and y decide where a point lies, so (3, 4) is in the first quadrant and (-3, 4) is in the second.
📈 Line and linear graphs
A line graph joins points to show change over time. A linear graph such as y = 2x is a straight line through the origin, and a steeper distance-time line means a faster speed.

This page covers Introduction to Graphs: Coordinates and Line Graphs for Class 8 maths. It covers coordinates and axes, plotting points, the four quadrants, plotting, line graphs, linear graphs and distance-time graphs.
The activities are pitched at Class 8 level. Sort points by axis, name quadrants, read line graphs and plot the line y = 2x on a grid in the studio. Explore more Class 8 maths worksheets on WitKnowLearn after this chapter.
Key ideas and facts to know
| Quadrant | Sign of x | Sign of y |
|---|---|---|
| First | + | + |
| Second | - | + |
| Third | - | - |
| Fourth | + | - |
How to use this page
- Flip the six cards and try the Graph Lab in the Learn tab.
- Play the five games and the five labs to practise each idea.
- Finish the five challenges to collect up to 15 points.
- Do two virtual experiments and plot the line y = 2x on a grid in the studio.
- Take the 20-question online quiz, with assertion and reason and case study questions, and fill in the practice sheet.
Worked examples
x is negative and y is positive, so it is in the second quadrant.
120 / 3 = 40 km per hour.

Coordinates and Line Graphs in daily life
Graphs are used in weather charts, sports scores, maps, speed and distance, school marks and any data that changes with time.
Tips for parents and teachers
- Plot x first, then y.
- Join points only when the graph is meant to be continuous.
- Practise one assertion and one case study each week.

Coordinates and Line Graphs Class 8 FAQs
What are coordinates?
Coordinates are an ordered pair (x, y) that gives the position of a point on a graph.
How do I plot (3, 2)?
Start at the origin, move 3 units right along the x-axis and then 2 units up.
How do I find the quadrant of a point?
Look at the signs: (+, +) is first, (-, +) second, (-, -) third and (+, -) fourth.
What does a linear graph look like?
A linear graph such as y = 2x is a straight line through the origin.
