Question

Match a standard form equation with the graph below.

Answer 1

Graph equations always start with y equals, using the graph, I found the gradient to be 1x and it went through 1 at the y intercept therefore I got the equation y=x+1

It is a because you have to rearrange it

Answer 2

Explanation:

Alright, lets get started.

There is a graph given and there are four equations given.

We are asked to determine which equation belongs to this graph.

When we see the graph, We see, at x = 0, y = 1

Similarly, when x = -1, y = 0

Lets plug these conditions into the equation given:

`x-y=-1`

`0-y=-1`

`y=1`

This satisfied the condition, similarly,

Lets plug x = -1

`-1-y=-1`

`y=0`

Which satisfies the condition.

So the equation is :
`x-y=-1` : Answer A

Hope it will help :)
