The answer to your question is B
A translation down to the left since it’s negative
Answer:
<h3>√(1-a)²+(b+2)²</h3>
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
<em>Hence the expression that represents the shortest distance between N and P in units is √(1-a)²+(b+2)² units</em>
