Question

Use the graph to write an equation that represents the relationship between X and Y.​

Answer 1

The equation is
`y=x-3`

Explanation:

Observing the graph

Let

`A(3,0), B(15,12)`

step 1

Find the slope m

`m=(12-0)/(15-3)=12/12=1`

step 2

Find the equation of the line into point slope form

`y-y1=m(x-x1)`

with the point
`A(3,0)` and the slope
`m=1`

substitute

`y-0=(1)(x-3)`

`y=x-3`
