Which line would be perpendicular?

Answer 1

Answer:

• D. -2x + 2y = 1

Step-by-step explanation:

When the line is given in standard form:

• ax + by = c, it has slope of -a/b

Given line:

• 4x + 4y = 3

It has a slope:

• m = -4/4 = -1

A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given

Let's see which line has the slope of 1:

• 1. m = -(-1)/6 = 1/6 - NO
• 2. m = -4/4 = -1 - NO
• 3. m = -2/4 = -1/2 - NO
• 4. m = -(-2)/2 = 1 - YES

Correct option is D
