Answer to Problem 46PPS
Time (months) | Length of hair (inches) |
0 | 8 |
3 | 9 |
6 | 10 |
9 | 11 |
Explanation of Solution
Given:
Her hair was 8 inches long and in three months it grew another inch at a steady rate.
Concept Used:
Equation of the line passing through the points
Calculation:
Given that initially her hair was 8 inches long and every three months the length of hair grows by 1 inch.
A table representing her hair length is shown below:
Time (months) | Length of hair (inches) |
0 | 8 |
3 | 9 |
6 | 10 |
9 | 11 |
b.
The graph showing the relationship between her hair length and time in months.
