Sun is using a projector to show a rectangle to the class. She is changing the distance from the projector to the screen so it is clear for everyone to see. The graph relates the length of the rectangle, l, to its width, w.
Dimensions of the Rectangle
On a coordinate plane, the x-axis is labeled Width of rectangle (centimeters) and the y-axis is labeled Length of rectangle (centimeters). A line goes through points (1, 1.4) and (2, 2.8).
According to the graph, which must be true?
The width of the rectangle is always 0.7 times the length of the rectangle.
The width of the rectangle is always 1.4 times the length of the rectangle.
The length of the rectangle is always 0.7 times the width of the rectangle.
The length of the rectangle is always 1.4 times the width of the rectangle.
