Question 1102782
9x+3y=-22
slope intercept form
3y=-9x-22
divide by 3 to make y=1
y=-3x-22/3
any line of the form y=-3x + something will be parallel to this line unless it is y=-3x-22/3, in which case it is the same line.
parallel lines have the same slope.
====================================
the slopes of perpendicular lines have a product=-1
for the negative reciprocal, flip the fraction and change the sign.
the second one I will assume is written as 7x+14y=-8
14y=-7x-8
y=(-7x/14)-(8/14) =(-1/2)x-(8/14)
perpendicular line will have slope +2/1 or +2
It will have the form y=2x+ some number.
