4x+3y=10
3x-4y=8
put these in the form
y = m x + b
where m is the slope
and b is the y axis intercept (y when x = 0)
3 y = -4x+10 --> y = (-4/3)x + 10/3
4 y = 3x-8 --> y = (3/4) x -2
Note that the second slope = -1/the first slope
so
The two lines are perpendicular.
parallel, neither , or perpendicular
4x+3y=10
3x-4y=8
