Janet is swimming to the other side of a lake and makes a graph of her progress.
On the graph, time is on the x-axis and distance from er starting point is on the y-axis the intervals of the grpah are described below
*Interval 1: Janet swims the first 100 meters from her starting point at a constant speed for 3 minutes
*Interval 2: Janet stops to take a 1-minute break.
*Interval 3: Janet swims the nest 100 meters at a constant speed for 2 minutes.
Use the drop--down menus to complete the statements that describe different intervals of the graph.
Interval 3 is A: Linear Or B: nonlinear?? A. Decreasing or B: increasing??
And the slope of interval 3 is A. steeper than? B. as steep as? C. not at steep as? the slope of interval 1.
"constant speed" means it's linear
interval 2 is a horizontal line segment, since distance is not changing
for this graph, slope = distance/time
liner
Interval 3 is B: nonlinear. The slope of interval 3 is C: not as steep as the slope of interval 1.
Interval 3 is B: nonlinear. This is because the graph is not a straight line but rather curved.
The slope of interval 3 is B. as steep as the slope of interval 1. This means that the rate at which Janet is swimming during interval 3 is the same as the rate at which she was swimming during interval 1.
