Question

Help me understand this.

Answer 1

the standing line is the "Y line"

the line laying down is the "X line"

wherever the line touches on the y and x line is where it intercepts

for the x it intercepts at 25 since it touches the x line between 20 and 30

for the y line it intercepts at - 55 since it touches the y line in between - 50 and - 60
