Question

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

Answer 1

Answer:

The equation is  $y=x-3$

Step-by-step 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

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

$y=x-3$
