Answer:
A
Step-by-step explanation:
Answer:
y = -3/2x + 11
Step-by-step explanation:
2x - 3y = 21 => 3y = 2x - 21 => y = 2/3x - 7
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of perpendicular line is -3/2
y = mx + b
y = -3/2x + b
Using (2,8)
8 = -3/2(2) + b
8 = -3 + b
b = 11
y = -3/2x + 11
Answer:
1. Answer is D) (1, -3)
