The midpoint of line

ab

is m(3, 3). if the coordinates of a are (2, -1), what are the coordinates of b?

( 4,7)

Step-by-step explanation:

The midpoint of Line AB is M(3, 3). The co-ordinates of B are (4, 7)

Solution:

Given that, the midpoint of Line AB is M(3, 3)

And the coordinates of A are (2, -1)

We have to find what are the coordinates of B

Substituting the values we get,

Hence, the co – ordinates of B is (4, 7)  

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.
