Equation for the given table.
Answer to Problem 29PPE
The equation for direct variation is
Explanation of Solution
Given data:
Table of the x v/s y.
Formula used:
Direct variation equation:
K is a constant.
Calculation:
As y is increasing with x at a difference of 5 units so it is a direct variation:
x | -2 | -1 | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
y | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
The graph of the equation is:
So it is a direct variation as graph is a straight line.
Conclusion:
The equation for direct variation is
