Answer:
-1/2
Step-by-step explanation:
To find the slope of the line, you subtract y2 - y1, and x2 - x1.
When coordinates are written, the x value is the first, and the y value is the second. So, for the point (1, 11), 1 is the x value and 11 is the y value.
So, we can subtract 10, the y value from the second point, and 11, the y value for the first point.
10 - 11 = -1.
Now, we can subtract 3, the x value from the second point, and 1, the x value from the first point.
3 - 1 = 2
So, we did y2 - y1 and got -1, and we did x2 - x1 to get 2.
The answer from subtracting the y values goes on top of the fraction, and the answer from subtracting the x values goes on the bottom.
-1/2
