A line is perpendicular to y=-1/2x-1 and intersects the point (6, 9). What is the equation of this perpendicular line?

Statement: if two points are given, then exactly one line can be drawn through those two points. which geometry term does the statement represent? defined term postulate theorem undefined term

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

Can some one explain this i got sent this. is this a threat i’m scared
