An equation is used to show two expressions that are equal to each other.

Plotting coordinates generated from a rule

Maths

In this unit, pupils extend their knowledge of plotting coordinates from KS2 by now plotting non-integer values. Pupils learn that a set of points can satisfy a relationship and this understanding is built on in the sequences unit

In this unit, pupils learnt how to plot coordinates in all four quadrants via plotting positions and then shapes

Plotting coordinates

A rule for a set of coordinates can be written as an __________.

Match the equation to the coordinates that follow the rule.

The $$y$$ coordinate equals the $$x$$ coordinate minus 4

The $$y$$ coordinate equals the $$x$$ coordinate multiplied by 5

The $$y$$ coordinate equals the $$x$$ coordinate divided by 5

The $$x$$ coordinate equals the $$y$$ coordinate multiplied by 5

The $$x$$ coordinate equals the $$y$$ coordinate plus 4

What is the rule for the coordinates $$(0,0)\;(5,1)\;(-10,-2)\;(15,3)$$?

Fill in the missing value in the following coordinate so it follows the rule: $$y=x + 3.5$$ $$\quad$$ $$($${{}}$$, 6.7)$$

Which of these rules match the graph shown? 

$$(1,1)\;(-6.2,6.2)\;(-7.1,-7.1)\;(2.5,-2.5)$$

Which set of coordinates will make a straight line when plotted?

In the coordinate $$(-6,4)$$, what is the value of the $$y$$ coordinate?

On the graph shown, which is the correct plotting of the coordinate $$(-2,2)$$?

The $$x$$ and $$y$$ coordinate are both 4

The $$y$$ coordinate is 4 and the $$x$$ coordinate is 1

The $$x$$ coordinate is 4 and the $$y$$ coordinate is 1

Which equation represents the sentence '$$y$$ is 3 less than $$x$$'

Which equation represents the sentence '$$x$$ is 4 lots of $$y$$' 

Match the calculation with the correct answer.
