Answer 2

What's the distance from the point X to the line y = 1 ?

Answer 3

in other words, how many units do you have to go up to go from X to the line y = 1 ?

Answer 4

x' coordinate will be 3
because x cood of x is 2 down from y=1

Answer 5

the distance of point x from y=1 is 2 units up

@jim_thompson5910
