Explanation:
#"consider the 2 equations expressed in "color(blue)"slope-intercept form"#
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#y=2x-3to(1)#
#y=2x+3/2to(2)#
#"both lines have "m=2#
#• " Parallel lines have equal slopes"#
#"the 2 lines are therefore parallel and never intersect"#
#rArr" there is no solution"#
graph{(y-2x+3)(y-2x-3/2)=0 [-10, 10, -5, 5]}
