Answer:
y=3x+6
Step-by-step explanation:
formula is, y-y1=m(x-x1)
3= slope or (m), (0,6), 0=x1 6=y1
y-6=3(x-0) --->distribute
y-6=3x-0 ---> get y alone
+6 +6
y=3x+6
Y=mx+b is our base equation
m=slope, so let's find that first:
m= change in y/change in x
So between the points (-1,-2) and (3,4),
The y values, -2 and 4, have a difference of 6. The x values, -1 and 3, have a difference of 4. This makes our slope 6/4 (or 3/2 simplified)
Now our equation is
Y=3/2x + b
We still need to find b
To find b, we can substitute a point given to us. Let's use (3,4) just to avoid negatives.
4=3/2(3) + b
Multiply
4=9/2 + b
Subtract 9/2 from both sides
-1/2=b
Now let's put it all back together!
Y=3/2x-1/2 Is the answer.

Answer:
n=9998
Step-by-step explanation:
I'm assuming you meant log base 10 and then n+2
-2 + log(n+2)=2
add 2 both sides
log(n+2) =4
10^4 = n+2
10000-2 = n
n = 9998
