Description: Sal plots the corners of a rectangle on the first quadrant of a coordinate plane. 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 seven, which says hey we need to move seven up from there. 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 to take a horizontal line, if you were to go straight to the left, you get to y equals seven. So let's line, lemme take this point right over here.*Teacher Advisor is 100% free.
