The slope of Consider the line whose equation is 3x + y - 3 = 0. The slope of any line that is parallel to this line is any line
PSYCHO15rus [73]

Answer:

parallel : y = -3x + 3

perpendicular : y = 1/3x + 3

Step-by-step explanation:

rewrite 3x + y - 3 = 0

y = -3x + 3

parallel has the same slope

so

parallel : y = -3x + 3

perpendicular is negative reciprocal of the slope

so

-3x becomes 1/3x

so

perpendicular : y = 1/3x + 3
