A rectangle in the coordinate plane is shown below. A line with slope 2 splits this rectangle into two regions with equal area. What is the y-intercept of this line?
The rectangle has coordinates (-1,-1), (-1,1), (1,1), and (1,-1).
Note that [BEFA] = [CEFD]
The line is y= 2x
Any line of the form y = ax will split the rectangle ( a square) into = areas and will have a y intercept = 0
