Answer:

Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:

Our first point, A, is at (1, 1) and our second point, B, is at (-2, 8).
Let's let A(1, 1) be (x₁, y₁) and B(-2, 8) be (x₂, y₂). Substitute this into the distance formula:

Subtract:

Square:

Add:

This cannot be simplified.
So, the distance between the two points is √58 or about 7.6 units.
And we're done!
