# Plotting corners of a rectangle

## Thuyết minh video

the four corners of a rectangle are located at the point 11 comma 711 comma 0 2 comma 0 and 2 comma 7 plot the four corners of the rectangle on the coordinate plane blown they have these dots and we can actually move these around for the four corners of our rectangle so let's look at this first point 11 comma 7 where will that go well let's just remind ourselves that the first coordinate here that is our x coordinate that tells us how far we move in the X direction or how far we move to the right so our x coordinate is 11 so we can say we can start at the origin and move 11 to the right and then our y coordinate is 7 which says hey we need to move 7 up from there so 1 2 3 4 5 6 7 so notice 11 that's if you were to just drop a line straight down you would hit the x-axis at 11 and the y coordinate if you were take a horizontal line if you go straight to the left you get 2 y equals 7 so there's the point 11 comma 7 alright let's do the next one then you have 11 comma 0 so let's let me take this point right over here so the x coordinate is once again 11 but the y coordinate is 0 which means we don't move up at all in the or we don't move up at all if we want me to think about it start at the origin you move 11 to the right and you move 0 up so this is going to sit on the x axis right over there 11 comma 0 all right that we have 2 comma 0 so x coordinate is 2 and we don't move up at all so we're going to sit on the x axis we move two to the right and 0 up or you can think of it 0 up and 2 to the right then we have 2 comma 7 so x coordinate is 2 but then we want to move equity's to that we want to move 7 up to get right over there and so you can see the corners of a rectangle right over here and then they ask us what is the height of the rectangle well let's see if we're from y equals zero to y equals seven so the height is seven you can even count it one two three four five six seven so the height of the rectangle is seven and then of course I can check my answer and I got it right
