Expert Solution

Step 1: Given information

$y equals negative 1 half x$

Take any point on this line on the 2nd Quadrant.

for x = -2, y = 1

By Pythagoras Theorem $A C equals square root of x squared plus y squared end root equals square root of left parenthesis negative 2 right parenthesis squared plus left parenthesis 1 right parenthesis squared end root equals square root of 4 plus 1 end root equals square root of 5$
