I think it is 1! I did it like this. 9•9• 9=1
I put period but it is the division sign
Slope: (y2-y1)/(x2-x1)
(-13-(-7)) = -6
-6/3 = -2
x - 3 = 3, x = 6
The solution: x = 6
-1 only (this is to to reach the character limit)
Answer:
A and C
Step-by-step explanation:
A) y = (1/2)x + 2 {Compare with y =mx +b}
slope = (1/2)
C) y = -2x + 4
Slope = -2
When product of two slopes is (-1), then the lines are perpendicular.
