    Without graphing does this system of equations have 1 solution, no solution, or infinite solutions? Y=3 x +5 y=3 x-5 and y=2 x +7 y=3 x — 1

    Y=3 x +5 y=3 x-5Since, slope is the same and the y-intercepts are different, these are parallel lines and they never meet. So, this system of equation has no solution! Y=2 x +7 y=3 x — 1Since, slope is the different same and the y-intercepts are different, these are not parallel lines and they meet at some point. Also, these are straight lines. So, this system of equation has one solution!
