To find:
The three values of c for which both the x -intercept and the y -intercept are integers. How are your values of c related to the coefficients of x and y in the given equation?
Answer to Problem 31E
The required three values of c would be
The values of c will decide the x - and y -intercept of our given equation.
Explanation of Solution
Given:
An equation:
Calculation:
Upon looking at our given equation, we can see that it is in standard form of equation
We know that to find x -intercept, we substitute
The value of c will be numbers, which are multiples of both 4 and 6 or divisible by both 4 and 6.
We know that least common multiple of 4 and 6 is 12.
Therefore, our required three values of c would be
The values of c will decide the x - and y -intercept of our given equation.
