Answer:

To find the distance between two points in a two-dimensional plane, we can use the distance formula:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, the two points are (-1, 1) and (-7, 1)

So the distance between them is:

Distance = √((-7 - (-1))^2 + (1 - 1)^2)

Distance = √((-6)^2 + (0)^2)

Distance = √(36 + 0)

Distance = √36

Distance = 6

Therefore, the distance between the two points (-1, 1) and (-7, 1) is 6 units
