Answer:
The equation to represent the rate of receding water level is L = 34
.
Step-by-step explanation:
Given as :
The initial level of water in river = 34 feet
The rate of receding water level = 0.5 foot per day
Or, The rate of percentage of receding water level = 50 % per day
Let the level of water after d days = L
Now,
The level of water after d days = initial level of water × ( 
I.e L = 34 × (
∴ L = 34 × 
Hence The equation to represent the rate of receding water level is L = 34

Answer:
The equation in the standard form is

Step-by-step explanation:
Given the points
Finding the slope between (6, -7) and (4, -3)




As the point-slope form is defined as

substituting the values m = -2 and the point (6, -7)


Writing the equation in the standard form form
As we know that the equation in the standard form is

where x and y are variables and A, B and C are constants
converting the equation in standard form


subtract 7 from both sides



Therefore, the equation in the standard form is

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

- point-slope form
Covert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>add 1 to both sides</em>
- slope-intercept form
Convert to the standard form (Ax + By = C):
<em>multiply both sides by 2</em>
<em>subtract x from both sides</em>
<em>change the signs</em>
- standard form
Convert to the general form (Ax+By+C=0):
<em>add 4 to both sides</em>
- general form
