n 5 seconds. Sketch and label a graph showing the car’s speed over time
1 answer:
Answer:
It is given that a car traveling at 23 mi/h accelerates to 46 mi/h in 5 seconds.
This means that in 5 seconds it's speed continuously increases to reach 46 mi/h from 23 mi/h.
It maintains that speed for 5 seconds and then slows to a stop in 5 seconds.
This means that the speed of the car is constant i.e. 46 mi/h i.e. the graph is a straight horizontal line parallel to the time axis.
And then it decreases to reach 0 mi/h.

Answer:
The equation of the line is:
Step-by-step explanation:
Given the points
- (-3, 8)
- (4, 1)
Finding the slope between the points
Using the point-slope form of the line equation
where m is the slope
substituting the values m = -1 and the point (-3, 8)
Add 8 to both sides
Therefore, the equation of the line is:
