Seasonal __ 125+3.50d=C
D= the number of days they went and C =the total cost of the trip
Answer:
The equation of required line is: 
Step-by-step explanation:
We need to write equation in the form Ax+By+C=0 of the line parallel to
and through the point (-2,3)
First we need to find slope and y-intercept of the required line.
Using equation of line
to find slope.
Since the given line and required lines are parallel there slope is same.
Writing equation in slope intercept form:
where m is slope.

So, the slope m = 5/8
The slope of required line is 
Now finding y-intercept using slope
and point(-2,3)

So, the equation of required line having slope
and y-intercept 

So, The equation of required line is: 
Supplementary is when it is a straight line that is equal to 180 degrees and complementary is a right angle which is 90 degrees
