How far from the origin is the point (-5, -12)?

The origin is (0,0)

so it is 5 units left from orogin and 12 units down
if we were to start from the origin, and draw a line that is 5 units long to the left, then draw a line that is 12 units down from that point, then connect the end point to the origin we get a triangle

legs are legnth 12 and 5
hypotonuse=?
12^2+5^2=?^2
144+25=?^2
169=?^2
sqrt both sides
13=?

answer is 13 units

or use distance fomrula
which is overkill
distance between ponts (x1,y1) and (x2,y2) is
D=
in this case, between (0,0) and (-5,-12)
D=
D=
D=
D=
D=13

asnswer is 13 units (distance is always positive)

The total would be 40.53
