Question 617155: how do you find out if these two lines are parallel,perpendicular or neither
y= 3/8x -4
8x + 3y=10
Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
the 1st equation is in slope-intercept form (y = mx + b)

solving the 2nd equation for y ___ y = (-8/3)x + (10/3)

the x-coefficients (slopes) of the two slope-intercept equations are negative-reciprocals
___ this means that the lines are perpendicular
