Answer:
The ordered pair is not a solution of the equation
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation, then the ordered pair must satisfy the linear equation
we have

Substitute the value of x and the value of y of the given ordered pair in the linear equation and analyze the results
For x=-1, y=15


 ----> is not true
 ----> is not true
so
the ordered pair not satisfy the equation
therefore
The ordered pair is not a solution of the equation
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Given
The attached graph
Required
What does x-coordinate of 2 represents
Represent this coordinate with (x,y)
From the graph:
 when
 when 
Note that:
x = time and y = distance
So:

Which means:
At 2 seconds, the train has travelled a distance of 120ft
<em>From the list of options, (c) is correct</em>
