A line passes through the point (8,-9) and has a slope of -5/2. Write an equation in slope intercept form for this line.
1 answer:
Answer:
y = - x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - , then
y = - x + c ← is the partial equation
To find c substitute (8, - 9) into the partial equation
- 9 = - 20 + c ⇒ c = - 9 + 20 = 11
y = - x + 11 ← equation of line

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
