Remember : you have to do your own homework.

I just provide you the way how to calculate your answer.

Draw X and Y lines

Mark P1 (-0.3,2.1) and P2 = (1.2,1.3)

Connect P1 and P2

Draw triangle from P1 horizontal and vertical from that line to P2

Calculate the horizontal and vertical sides of this triangle.

Calculate than the hypothenusa of this triangle (which is line P1 to P2)

Calculate the half value of this line.
