Step-by-step explanation:
Hello! I hope you are having a nice day. My name is Galaxy and I will be helping you today.
We can solve this problem in a single step, we just need to know how equations like this are set up.
Equations in slope intercept form are set up in form. With
being the slope of the line, and
being the y intercept.
In your problem, we need to find the value of , which is the y intercept.
The y intercept is what is y when x is zero. We can find that by looking at the graph supplied.
When we look at the line, we can see that it hits the x axis when y is negative two, therefore the intercept is .
Since we know that, we can reconstruct our equation with this information, we already know the slope so we can add in -2 to get our answer.
This would be our final answer.
Cheers!
