Question

How do you graph `y-x=0`?

Answer 1

see explanation.

Explanation:

The equation `y-x=0` may be written as follows.

add x to both sides of the equation.

`ycancel(-x)cancel(+x)=0+x`

`rArry=x" is the equation"`

This tells us that the x and y coordinates are equal.

To graph, choose values of x

`x=-2toy=-2rArr(-2,-2)" is a point on graph"`

`x=0toy=0rArr(0,0)" is a point on graph"`

`x=3toy=3rArr(3,3)" is also a point on graph"`

Plot these 3 coordinate points and draw a straight line through them. Thus you have the graph of y - x = 0
