Line ℓ1 has the equation y=x–5 and line ℓ2 has the equation y=x–1. Find the distance between ℓ1 and ℓ2. round your answer to the nearest tenth

and are parallel to one another with slope 1. Any line with slope -1 is perpendicular to both of these lines, the simplest being .

This perpendicular line intersects and at the points (5/2, -5/2) and (1/2, -1/2), respectively.

The distance between and is the same as the distance between these two intersections:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
