the graph represents the journey of a bus from the bus stop to different locations:

in which parts of the graph is the function increasing, decreasing, and constant? (4 points)

The parts where it is increasing, decreasing or constant are given below.

It is not a straight line at 1, 3 and 5 so it is non-linear at those parts and it is straight line at 2 and 4 so, it is linear at those parts.

Step-by-step explanation:

The graph of the function is,

1. increasing at 1 and 5

2. decreasing  at 3

3. constant at 2 and 4.

It is not a straight line at 1, 3 and 5 so it is non-linear at those parts and it is straight line at 2 and 4 so, it is linear at those parts.

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

the correct answer is d

hope this
