Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
n-2-(10*n+42)=0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-9n - 44 = -1 • (9n + 44)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -9n-44 = 0
Add 44 to both sides of the equation :
-9n = 44
Multiply both sides of the equation by (-1) : 9n = -44
Divide both sides of the equation by 9:
n = -44/9 = -4.889
One solution was found :
n = -44/9
n - 2 = 10n + 42
Add 2 to both sides:
n - 2 + 2 = 10n + 42 + 2
Simplify:
n = 10n + 44
Subtract 10n from both sides:
n - 10n = 10n + 44 - 10n
Divide both sides by -9:
-9n/-9 = 44/-9

C
- choose any 2 sets of corresponding values and use the formula
( y2 - y1 ) / ( x2 - x1 )
you'll get -3/4
