You move left 3 units and right 4 units. You end at (0, -5). Where did you start?

Question

8th Grade Math, Massachusetts, U.S.

Answer 1

left 3, right 4 is the same as right 1

right 1 means add 1 to the x coordinate

if you end with (0,-5) you started at (-1,-5)

going left or right only changes the point horizontally.

the y coordinate remains the same

start at (-1,-5) move left 3 means (-1-3,-5) = (-4,-5)

then move right 4 means (-4+4,-5) = (0,-5)= ending point

changes left and right are changes in x

changes up or down are changes in y

left 3 means subtract 3 from the x coordinate

right 4 means add 4 to the x coordinate

if there's no up or down, the y coordinate stays the same
