Question 995011: Determine which functions have graphs parallel to each other. Name two of the functions whose graphs that intersect. Linear functions are expressed by formulas:
a) y=-20x+13, y=3.7x-13
b)y=-8-20x, y=-3.6x-8, y=3.6x+8 , y=-3.6x
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
parallel lines have the same slope
a: NOT parallel, for they have different slopes. They do intersect.
You can determine that point by setting them equal to each other.
-20x+13= 3.7x-13
-23.7x= -26
x=(26/23.7)
======
b. The third, and fourth functions are all parallel, for they both contain y=3.6x.
====
For every one of the five functions given.
y=-20x+13 is parallel to y=-8-20x
y=3.6x+8 and y=3.6 x are parallel to each other.
