Answer:
Y=-3X-1
Step-by-step explanation
Find where the line intersects the vertical line according the the horizontal line (-1)
The slope (-3X) is found by making a triangle where the line hits corners of squares. This is negative because it is beneath the horizontal line.
The slope is negative because it's slopes down to the right. It would be positive if it slopes down to the left.
