Answer:

The equation is  [tex]y=x-3[/tex]

Step-by-step explanation:

Observing the graph

Let

[tex]A(3,0), B(15,12)[/tex]

step 1

Find the slope m

[tex]m=(12-0)/(15-3)=12/12=1[/tex]

step 2

Find the equation of the line into point slope form

[tex]y-y1=m(x-x1)[/tex]

with the point [tex]A(3,0)[/tex] and the slope [tex]m=1[/tex]

substitute

[tex]y-0=(1)(x-3)[/tex]

[tex]y=x-3[/tex]
