Question

Question 8 According to a textbook, this is a challenging question; according to me, it is the easiestquestions, among the easy questions!Suppose that the equations ax + by = c, where a, b, and c are real numbers, describes a directvariation. What do you know about the value of c?That c is

Answer 1

The Solution:

Given the equation below:

`ax+by=c_{}`

We are asked to say what we know about the value of c.

From the above equation, it is clear that:

c is a variable that depends on the values of the variables x and y.(where a and b are possibly constants.
