Using the rate of change concept, it is found that it will be negative on the interval in which the function is decreasing.

<h3>What is the rate of change of a function?</h3>

The rate of change, considering two points, is given by the change in the output divided by the change in the input.

Hence:

If the rate is negative, the function is decreasing.

If the rate is positive, the function is increasing.

Transform both equations in each system of equations so that each coefficient is an integer.

inysia [295]

For the first one multiply each term by the LCM of 4 and 6, which is 12:-

15x -36 = 2y..................(1)

and second multiply by 5:-

2x + y = 9..............(2)

solving:-
from equation (2) y = 9-2x, substitute in equation (1):-

15x - 36 = 2(9-2x) = 18 - 4x
19x = 54
x = 54/19 = 2.84

so y = 9 - 2(2.84) = 3.32
