The linear model is represented as
A. An increasing lines goes up from left to right. This is shown from 0 to 2
B. A horizontal line would show the height remaining the same. This is shown from 2 to 3
C. The steeper the line the faster the decrease. This is shown from 3 to 4
D. The height of the balloon at 10 seconds would be O as it hits the zero mark at 6 seconds and the arrow continues along the O line.
What is Linear Model ?
A linear model is an equation that describes a relationship between two quantities that show a constant rate of change.
Part A the balloons height is increasing when the line is going up
It is increasing between 0 and 2
0 ≤ t ≤ 2
Part B the balloons height remains the same when the line is flat
It is constant between 2 and 3
2 ≤ t ≤ 3
Part C the balloons height is decreasing when the line is going down
It is decreasing the fastest when the line is going down the quickly and that is between 3 and 4. The slope is (80-20)/(4-3)= 60/160. The larger the slope, the faster the height decreases.
3 ≤ t ≤ 4
Part D At 10 second the balloon will be on the ground. At 6 second the height is zero and remains at 0.
