Let gradient of original line = m = 1/6
Gradient of line perpendicular to this = -1/m = -6
(Gradient = slope)
Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
Answer: a = 4/3
Step-by-step explanation:
1. a/4 − 5/6= −1/2 convert -1/2 to -3/6
2. a/4 = 5/6 - 3/6 = 2/6 = 1/3
3. a = 4*2/6 = 4*1/3
4. a = 4/3
