y - 2x = -1 y = 2x + 1 graph of this line : y int = (0,1) ....x int = (-0.5,0)...slope = 2....this is a positive slope so ur line is increasing (going up)....points on this line will include : (-1,-1) , (1,3) , (2,5)....now plot these points and connect the dots. x + 3y = 4 3y = -x + 4 y = -1/3x + 4/3 graph of this line : y int = (0,4/3)...x int = (4,0)...slope = -1/3...this is a negative slope so ur line is decreasing (going down)....points on this line include : (-2,2) , (-5,3) , (7,-1)...now plot these points and connect the dots since I do not have a picture of the graphs, this is all I can do
