Answer:
y axis denotes the level of water in cylinder
x axis denotes the time
Step-by-step explanation:
Given : At 1 p.m. cylinder is 80% full i.e. 0.80.
At 2 p.m. cylinder is 65% full i.e. 0.65.
Solution :
time(x) : 1 2
level (y) : 0.80 0.65
Using these points we can plot the graph (refer the attached figure)
In the figure y axis denotes the level of water in cylinder
x axis denotes the time
We can also find the equation of the graph by using two point slope form :
\(y-y_{1} =m(x-x_{1})\) ---a
Where m is the slope
\(m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}\)
Since \((x_{1} ,y_{1}) =(1,0.80)\)
\((x_{2} ,y_{2}) =(2,0.65)\)
Thus slope (m) =
\(m=\frac{0.65 -0.80}{2-1}\)
\(m=-0.15\)
Now putting values in equation a
\(y-0.80 =-0.15(x-1)\)
\(y-0.80 =-0.15x+0.15\)
\(0.15x+y-0.95=0\)
Thus the required equation of the situation or the graph is
\(0.15x+y-0.95=0\)
THE GRAPH IS ATTACHED AND Y INTERCEPT DENOTES THE LEVEL OF WATER
