Answer:5y=x-35
Step-by-step explanation:
The given line passes through the points
,
.
Let the slope of the line be
.
If a line passes through
and
,then

So,
Y-intercept of a line is defined as the y-coordinate of the point where the line touches y axis.
Let the y intercept be 
From the graph,
The equation of the line with slope
and y-intercept
is 
So,

Answer:

Step-by-step explanation:
GIVEN: A farmer has
of fencing to construct a rectangular pen up against the straight side of a barn, using the barn for one side of the pen. The length of the barn is
.
TO FIND: Determine the dimensions of the rectangle of maximum area that can be enclosed under these conditions.
SOLUTION:
Let the length of rectangle be
and
perimeter of rectangular pen 


area of rectangular pen 

putting value of 


to maximize 



but the dimensions must be lesser or equal to than that of barn.
therefore maximum length rectangular pen 
width of rectangular pen 
Maximum area of rectangular pen 
Hence maximum area of rectangular pen is
and dimensions are
