Answer:
20
Step-by-step explanation:
i did this on a hw equation
The equation for working out the slope of a linear line is: 
, where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do 
, which is just 
when simplified.
For a logarithmic function, we have a restriction on the domain.
Since log(0) isn't defined, we say that there is an asymptote at x = 0.
Thus, for the regular logarithmic function y = log(x), x > 0.
We can then say (x + 4) > 0, since that's when the function of a logarithm is defined as.
x + 4 > 0
x > -4
Thus, the domain of the logarithmic function is x > -4, where x is a real integer.
When grades are expressed as a quantity of 1, such as two feet per second or 5 miles per hour, they are called unit rates.
Lawns = L
Money he gets from mowing = M
M - $7 - (L * $1.50) = P for 1 Week
Hope this helped :D
