Question

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

Answer 1

Answer:

The correct option is B.

Step-by-step explanation:

If a line passing through two point $(x_1,y_1)$ and $(x_2,y_2)$, then the slope of line is defined as

$m=\frac{y_2-y_1}{x_2-x_1}$

It is given that the line is connecting points on ordered pair (1, 25) and (2, 50) and (3, 75) and (4, 100).

Consider any points of the line,i.e., (1,25) and (2,50). Then the slope of the line is

$m=\frac{50-25}{2-1}$

$m=\frac{25}{1}$

$m=25$

The slope and rate of change for the relationship represented in the graph is 25. Therefore the correct option is B.

Answer 2

Answer:

Step-by-step explanation:

The answer is 25 i think bc when yu do the steps yu will find out so i think the answer is 25 or 50 either one i am positive... if a i am wrong then my apologies i am just in 6th grade..
