Answer:
√(1-a)²+(b+2)²
Step-by-step explanation:
If the pipe on the plan runs from point N(a, -2) to point P(1, b), the expression that represents the shortest distance between N and P in units, is expressed using the formula;
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinates N(a, -2) and P(1, b);
x₁ = a, y₁ = -2, x₂ = 1 and y₂ = b
NP = √(1-a)²+(b+2)²
Hence the expression that represents the shortest distance between N and P in units is √(1-a)²+(b+2)² units
Using the distance between two points, it is found that the expression that represents the shortest distance between N and P in units is:
[tex]d = \sqrt{(1 - a)^2 + (b + 2)^2}[/tex]
Considering two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], the distance between them is given by:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
In this problem, the points are N(a, -2) and P(1,b), hence, their distance is:
[tex]d = \sqrt{(1 - a)^2 + (b - (-2))^2}[/tex]
[tex]d = \sqrt{(1 - a)^2 + (b + 2)^2}[/tex]
