Answer:
[tex]y = 2x - 2[/tex]
Step-by-step explanation:
You have not attached the graph.
Assuming the graph function is the one shown in the attachment.
The equation is given by
[tex] \frac{x}{a} + \frac{y}{b} = 1[/tex]
where a=1 is the x-intercept and b=-2 is the y-intercept.
We substitute to get:
[tex] \frac{x}{1} + \frac{y}{ - 2} = 1[/tex]
[tex]2x - y = - 2[/tex]
or
[tex]y = 2x - 2[/tex]
