Use the given information to determine the exact trigonometric value.

Jack has a rectangular piece of land, the area of which is represented by a1 = 9.5l. his brother has a different rectangular piece of land, the area of which is represented by a2 = l(14 − l). let a represent the area in square meters and l represent the length in meters of the pieces of land. the two equations plotted on a graph meet at a point as shown in the image

Suppose the equation of a line is 2x − 4y = − 8. which coordinate pair represents the y-intercept?
