Answer:

y =  -  \frac{2}{ 3} x +  \frac{1}{3}

Step-by-step explanation:

either pick the generic line in slope-intercept form

y = mx + q

and plug y and x from the points in there, you get two conditions on m and q and find the values or...

Between the two points you get that when x increases (from 2 to 5) by 3 units, y decreases (from -1 to -3) by 2 units. You can rule out the first two options since the slope cannot be an integer. from the other 2, try x=5 into both to see which one gives -3 for y.
