To solve this problem, we can use the formula for calculating slope:

slope = (change in y) / (change in x)

Given that the slope is unknown (as indicated by the blank in the question), we can write the equation for the slope as:

slope = (y - (-1)) / (6 - 10)

Simplifying the equation:

slope = (y + 1) / (-4)

Since the slope is -, we have:

- = (y + 1) / (-4)

To solve for y, we can cross-multiply:

- * (-4) = y + 1

4 = y + 1

Subtracting 1 from both sides:

y = 4 - 1

y = 3

Therefore, the value of y is 3.
