A(2, 7) is a fixed point in the coordinate plane. Let B(x, 7) be any point on the same hori-
zontal line. If AB = h(x), express h(x) in terms of x.

Respuesta :

If AB = h(x), then express h(x) in terms of x will be h(x) = (x - 2).

What is the distance between two points?

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x - h)² + (y - k)²  

A(2, 7) is a fixed point in the coordinate plane.

Let B(x, 7) be any point on the same horizontal line.

If AB = h(x), express h(x) in terms of x.

Then we have

h(x)² = (x - 2)² + (7 - 7)²

h(x)² = (x - 2)²

h(x) = (x - 2)
