What is the equation of the graphed function?
masya89 [10]
The correct answer is A.) f(x)=\frac{-1}{3}x+1

This is because using slope intercept form (y=mx+b), we can solve.

m = slope
b= y-intercept

If you look at the graph, you can see the line crosses they y-axis at 1.

And if you follow the line using rise over run, you find that it is 1/3.
But because it is a negative line, it makes the slope negative.

Hope this helps!
