Answer:
Option A. These two lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
step 1
Convert the given equation A in slope intercept form

where
m is the slope
b is the y-intercept
we have
----> equation A
Solve for y
That means----> isolate the variable y
Divide by 3 both sides

so

step 2
Convert the given equation B in slope intercept form

where
m is the slope
b is the y-intercept
we have
----> equation B
Solve for y
That means----> isolate the variable y
subtract 3x both sides
Divide by 2 both sides

so

step 3
Compare the slopes


The slopes are opposite reciprocal (the product is equal to -1)
therefore
These two lines are perpendicular
اختي هلق اذا نزلنا من الزاوية الثانية خط منحسن نلاقي مستطيل ونحيب مساحته ويلي هية ١٢ متر مربع
بعدين منطلع الضلعين الموجودين يلي لح يكونو نفس القيمة
يعني هوو كمان مستطيل ١٤×٤=٥٦
٥٦+١٢=٦٨
يعني الجواب ٦٨ متر مربع ان شاء الله يكون صح لاني حليته نظرياً
