The answer is 1,342 cm squared. This problem is fairly simple, but ok.
Plug into calculator...
solve(2(-y+1)-3y=-30,y)
y=6.4
Answer:
The required equation 
C should be correct.
Step-by-step explanation:
Given: Julissa is running a 10-kilometer race at a constant pace.
After running for 18 minutes, she completes 2 kilometers.
First point: (18,2)
After running for 54 minutes, she completes 6 kilometers.
Second Point: (54,6)
We need to write an equation letting t, the time in minutes, represent the independent variable and k, the number of kilometers, represent the dependent variable
Using two point formula to find the equation of line
Formula:

Required Equation:



Hence, The required equation 
It depends on what the graph shows. I need to see the graph to help you. sorry
