Find the distance between the pair of points (2, -5) and (3, -7)

Step-by-step explanation:

Using distance formula:

√(- 7 - (-5))² + (3 - 2)²

√(- 7 + 5)³ + 1²

√(-2)² + 1

√4+1

√5

sorry not sure

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
