Different characteristics of y = x

Question

 

What are the characteristics of the graph for this equation? (Select the 3 that apply.)

 

your answer

	The equation  is represented by a straight line that passes through the point (0,2).
	The equation  is represented by a straight line that passes through the origin (0,0).
	For the equation , the value of y will always equal the value of x.
	For the equation , the value of y will always be twice the value of x.
	For the equation , as the value of x increases, the value of y increases.
	For the equation , as the value of x increases, the value of y decreases.

only 3 of the characteristics are correct, can you help me figure out which ones are the wright ones? ( you may need a graph for this )

Answer 1

2nd, 3rd and 5th apply

y will always equal x

as x increases, y increases

x=y goes through the origin, the point (0,0)
