How do you find the coordinates of a point on as coordinate grid?

Answer 1

a coordinate grid is written as the horizontal line is the values of the x-coordinate and the vertical line is the values of the y-coordinate.

lets say you have the points (2,3)

whenever you see this ( , ) this is called an ordered pair. the x-coordinate always comes first and the y-coordinate comes second.. like this.. (x,y)

in the coordinate i gave as an examples (2,3) the 2 is the x-coordinate and 3 is the y-coordinate.

first take the x-coordinate. since the horizontal line is for the x-values then you apply the 2 to this horizontal line. the 2 implys that you go over 2 units. since the number 2 is positive you go to the right of the intersection of the two lines. if the two was -2 then you would go left.

now take the y-coordinate. since the vertical line is for the y-values then you apply the 3 to the vertical line. the 3 implys that you go up 3 units. since the 3 is positive then means you go up instead of down. if the 3 were a -3 then you would go down three units.

now that you have gone 2 units to the right and then 3 units up you should have a dot that is above the horizontal line and the dot should also be to the right of the vertical line.

always remember that the point at which your horizontal line (this is for your x-values) and your vertical line (this is for your y-values) is called the point (0,0) this is called the origin. when you are trying to find the coordinate points always start counting from the origin (0,0).
