Answer:
Step-by-step explanation:
The equation of a horizontal line is y = b where b is the y-intercept. Since the slope of a horizontal line is 0, the general formula for the standard form equation, y = mx + b becomes y = 0x +b y = b. Also ,since the line is horizontal, every point on that line has the exact same y value. This y-value is therefore also the y-intercept.
Set up as for portion with X as unknown number of gray cats. So 1/3=x/9. Cross multiply. 3X=9. Divide both sides by 3. X=3.
Answer:

Step-by-step explanation:
Let the exponential function be

We substitute (0,9) to get:



The equation now becomes:

We substitute (3,72) to get:



The equation is therefore

Answer:
m= -2n-13
Step-by-step explanation:
1. Subract 1 from both sides
m=-2(n+6)-1
2. Mulitply n+6 by -2
m=-2n-12-1
3. m=-2n-13
