<PRE><B>Question 510207</B>
these lines are parallel because they have the same slope


solving the equations for y, puts the lines into slope-intercept form (y = mx + b)
___ m is the slope of the line and b is the y-intercept (where the line crosses the y-axis)


5x=3y+3 ___ y = (5/3)x - 1


-10x+6y=3 ___ y = (5/3)x + (1/2)


if the slopes were negative-reciprocals of each other, the lines would be perpendicular


anything else would be neither</PRE>
