Question 46311
(1) The graph of y=3x+1 looks exactly like the graph ofy=2x , but shifted up 1 unit. 
ANSWER:  False.  y=3x+1 has a slope of 3/1 and the line is shifted 1 space to the left.  y=2x has a slope of 2/1 and has a y-intercept of (0, 0).

(3) The ordered pair (3,4) satisfies the equation 2y-3x=-6.
Answer:  Plug-in the values to test:  
2(4)-3(3)=-6
8 - 9 does not equal -6
False.
