infinite number of lines, so there is an infinite number of equations.
there are an infinite number of line that passes through the point (-2,5)
x=-2 is one line that passes through the point
y = 5 is another line that passes through the point
(these two lines are perpendicular to each other).
since the number of numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes. our only condition is that it passes through the point (-2,5)
mr. flanders’ class sold 47 doughnuts and mr. rodriquez’s class sold 38 cartons of milk
let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.
1. together, the classes sold 85 items, then
2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,
3. solve the system of two equations:
