Question

Determin whether the lines are parallel, perpendicular, or neither 

 

L1: 4x=3y+3

L2: 6y=8x+36

Answer 1

a.  find the slope of L1

b.  find the slope of L2

 

If these slopes are equal then the lines are parallel. If the product of these two slopes is -1, then the lines are perpendicular.  Otherwise neither.

 

How to find slopes?  In each case, "SOLVE FOR Y"--thus putting the equations in slope-intercept form; slope is coefficient of x if equation is in slope-intercept form.
