Answer:
-5/9
Step-by-step explanation:
Slope of line a is,
m = (1-10) / (1-6)
= (-9) / (-5)
= 9/5
Slope of line b is -1/m
-1/m = -1 / (9/5) = -5/9
Answer:
Slope of line b: -5/9
Step-by-step explanation:
(6,10) and (1,1)
m = (10-1)/(6-1)
m = 9/5

Hello!
3x - 32 = -7x + 28
-32 - 28 = -7x - 3x
-60 = -10x
-6 = -x
6 = x
x = 6
I hope this helps you! Have a lovely day!
