Question 54043
To graph x>4, draw a number line with zero in the middle, 4 on the right side of it and -4 on the left. 
x is greater that 4 so put an open circle on 4, and draw an arrow going to the right, meaning that any number greater than 4 can take the place of x and still make the inequality true. As for y=B, I'm not so sure, but good luck with your homework!!
