Answer: -3
Step-by-step explanation:
If you find where the line crosses the y-axis, and count to the next official and visible vertex, you will get 3 up or down, over 1 left or right. It's called rise over run. And as the line is drawn from the left to right side, it's a negative line.
The slope formula is y2 - y1 / x2 - x1, just put two order pairs into that formula and you'll find the slope. By the way the slope is -3.
