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]
