Answer: -2
Explanation: On the image we can see it goes down 4 units and right 2. Giving us the slope 
Simplified that is -2 which is the slope of the line
Answer: N=-4
Step-by-step explanation:
STEP

:
STEP
2
:
Pulling out like terms
2.1 Pull out like factors :
-4n - 9 = -1 • (4n + 9)
Equation at the end of step
2
:
-3 • (4n + 9) - 21 = 0

4
:
Pulling out like terms
4.1 Pull out like factors :
-12n - 48 = -12 • (n + 4)
Equation at the end of step
4
:
-12 • (n + 4) = 0
STEP
5
:
Equations which are never true:
5.1 Solve : -12 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.2 Solve : n+4 = 0
Subtract 4 from both sides of the equation :
n = -4
One solution was found :
n = -4
Answer:
1/4
Step-by-step explanation:
1/2 × 2/3
= 1×3 = 1
2×2 = 4
Therefore,
1/2 × 2/3 = 1/4//
