Answer:

3rd option Y= (-1/5)x+1

Explanation:

The y intercept is at 1. So eliminate the last option.

The slope is negative bc as x increases, y decreases. So eliminate the first option.

Now let's calculate the slope = (y2-y1)/(x2-x1)

Pick two points. let's use (1,1) and (5,0). I'm approximating just to get a rough idea of the slope.

= (1-0)/(1-5)= 1/-4. Now remember this is just a collection of points, so find the option closest which is -1/5.

So the 3rd option is the best choice.
