Answer:
A point that must lie on this line is the origin (0,0)
Step-by-step explanation:
we know that
The equation of the line in standard form is equal to

where
A is a positive integer
B and C are integer
In this problem
C=0
so

That means, that the line represent a proportional relationship between the variables x and y
Remember that in a proportional relationship the line passes through the origin
therefore
A point that must lie on this line is the origin (0,0)
It is an isosceles triangle
X+y=18
5x+y=62
x is number of five dollar bills and y is one dollar bills.
