Answer:
The slope of y = –3x – 4 is –3. The slope of the perpendicular line is the negative reciprocal. This means you change the sign of the slope to its opposite: in this case to 3.
Explanation:
7/2
The slope of perpendicular lines are opposite reciprocals
You have the slope -2/7, so the opposite reciprocal of this would be 7/2
Remember, opposite means you flip the sign, and reciprocal means you flip the fraction.
