A soccer ball is nicked upward from the ground and flies through the air with an initial vertical velocity of 4.9 meters per second. Approximately, after how many seconds does it land?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

table 3 represents a direct variation function. : )

answer: y = -2.5x - 15

              (-6,0)
