Question

Determine whether the given linear equations are parallel, perpendicular, or neither.


y = -9x +11

anonymous · Answer

y=1/9x+8  and y = -9x +11

anonymous · Answer

Can u find slopes of the lines?

anonymous · Answer

yes 1/9x and -9x

anonymous · Answer

when you multiply them you get -1

anonymous · Answer

hence they are perpendicular

anonymous · Answer

oh thanks!

Determine whether the given linear equations are parallel, perpendicular, or neither. 

8x - 4y = - 12 
8x - 4y = 8

anonymous · Answer

parallel right?

anonymous · Answer

if m1 is the slope of the 1st line and m2 is slope of second line

if m1 = m2  then two lines are said to be parallel
if m1*m2  = -1 then two are said to be perpendicular
if none of above satisfies then two lines are neither parallel nor perpendicular

Thank you! 

Write the equation of the line with a slope of 5 and a y-intercept of (0, 6) in slope-intercept form.
