The black line is the graph of y=x. Which of these equations could represent the blue line?

Here we can see that the blue line cuts exactly half way through the angle that the black line makes with x axisThat is all the x values are halvedWhich implies all the x value of the black line are divided by 2 to form the points on the blue lineso that give us the function [tex] y=\frac{1}{2} x [/tex]
