Explanation:
#"if we consider the 2 equations in "color(blue)"slope-intercept form"#
#•color(white)(x)y=mx+b#
#"where m is the slope and b the y-intercept"#
#-2x+y=1toy=2x+1rArrm=2#
#y=2x+3rArrm=2#
#"the 2 lines have the same slope and are therefore "#
#color(blue)"parallel"#
#"hence no point of intersection thus no solution"#
graph{(y-2x-3)(y-2x-1)=0 [-10, 10, -5, 5]}
