Horizontal and Vertical graphs

What is mean by the x co-ordinate mean?

• The coordinate on a graph labelled x

• The first number in the coordinate.

• The second number in the coordinate.

• Where a number is missing in a coordinate and we write x in it's place.

What is mean by the y co-ordinate mean?

• The coordinate on a graph labelled x

• The first number in the coordinate.

• The second number in the coordinate.

• Where a number is missing in a coordinate and we write x in it's place.

If I plotted 5 coordinates where the x coordinate is 3, for example (3,7) etc.

what 'pattern' would they create?

• A diagonal line

• A vertical line

• A horizontal line

• no pattern

If I plotted 5 coordinates where the y coordinate is 3, for example (7,3) etc.

what 'pattern' would they create?

• A diagonal line
