Answer:
y = -1/3x
Explanation:
To find the slope of the line, you can take two points and use the slope formula.
-2 - 0 = -2, 6 - 0 = 6, -2/6 = -1/3 which is the slope.
You would usually need to find b in y = mx + b but here you don't need b due to their being no y-intercept.
So just substitute -1/3 into y = mx + b
