Answer:
y= -6x
Explanation:
As you move up vertically from your y-intercept (0,0) six times, you can see that your x-intercept increased by -1. Because your x-intercept has increased by -1, there is a negative sign in front of 6x
There is no number after -6x because the place where your line meets the y-axis (y-intercept) is (0,0).
