Final Answer:
The rate of change of y with respect to x in the equation 25x - 4y = 50 is -6. Option C is answer.
Step-by-step explanation:
To find the rate of change of y with respect to x, we need to isolate y on one side of the equation. We can do this by rearranging the equation as follows:
4y = -25x + 50
Dividing both sides of the equation by 4, we get:
y = -6.25x + 12.5
Therefore, the rate of change of y with respect to x is -6.25, which can be approximated as -6.
Option C is answer.
