How can I draw it please ​

First take a scale and make a line down measuring up to 10 centimetres.

Then label one side as A and another one at the opposite as B.

Then measure 10cm at your compass while letting the point of the compass stay at point A.

Then letting it stay at A make a arc upward and another below.

Then put your compass at B again taking the same measurement of 10 cm.

Then putting the compass at point B make an arc to cross the previous arcs .

Then make a line between the center of two arcs making a perpendicular.

answer: -0.5 would be the most likley outcome
