What is the equation of a line perpendicular to the line given by y = (3/7)x+ 9
1 answer:
Answer:
B) y = (-7X/5) + 4
Step-by-step explanation:
Recall two lines are perpendicular if their slopes are negative reciprocals (5/7 goes to -7/5).
Assuming in the form y = mx + b:
Solving for b:
-7/5(-5) + x = 11
(5's & negatives cancel out...)
7 + x = 11
x = 4
y = -7/5x + 4
