PLEASE HELP!

The graph below shows the height an elevator travels, y, in x seconds:

A graph is shown with x axis title as Time in seconds. The title on the y-axis is Height of Elevator Above Ground in feet. The values on the x-axis are from 0 to 5 in increments of 1 for each grid line. The values on the y-axis are from 0 to 125 in increments of 25 for each grid line. A line is shown connecting points on ordered pair 1, 25 and 2, 50 and 3, 75 and 4, 100. The title of the graph is Rate of Ascent.

What is the rate of change for the relationship represented in the graph?

50
25
fraction 1 over 25
fraction 1 over 50

Respuesta :

The graph is not given , but with the help of information provided by you in the question:

X  :   0       1       2      3     4      5     →→ Time in Seconds

Y   :   0     25   50   75   100   125    →→Height of Elevator Above Ground in feet

Rate of change can be found by using two point slope form of line.

The slope of line joining two points [tex](x_{1},y_{1}) and (x_{2},y_{2})[/tex] is given by = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Taking two points (1,25) and (2,50) and finding the slope of line, that is Rate of change:

Rate of change = [tex]\frac{50-25}{2-1}=25[/tex]

Option (B) 25 is correct answer.



The rate of change of the relationship shown in the graph is 3 feet per second.

Linear equation

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the elevator height after x seconds.

From the graph using points (1, 10) and (4, 40):

m = (40 - 10)/(4 - 1) = 3

The rate of change of the relationship shown in the graph is 3 feet per second.
