The line of y=x-2 intersects the x axis at (2,0).
To find the points where line intersect the x-axis.
What is co-ordinate geometry?
Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.
The x-axis is defined as being at y=0 (look at a graph, the x-axis intersects the y-axis at y=0). Therefore, all you need to do is put in 0 for y, and solve for x.
y=x-2
put in 0 for y
0=x-2
add 2 to both sides
2+0=x-2 +2
x=2
Therefore the line of y=x-2 intersects the x axis at (2,0).
