Answer:
Rate of change: 25
Initial value: 25
Equation: y = 25x + 25
Step-by-step explanation:
✔️hours = x
Fee = y
Rate of change (m) = ∆y/∆x
Rate of change (m) = 25/1 = 25
Rate of change (m) = 25
✔️Initial value = y-intercept (b).
To find the initial value, simply substitute (x, y) = (1, 50) and m = 25 into y = mx + b.
Thus:
50 = (25)(1) + b
50 = 25 + b
Subtract 25 from each side
50 - 25 = b
25 = b
b = 25
✔️To write an equation, substitute m = 25 and b = 25 into y = mx + b.
Thus:
y = 25x + 25

Answer:
f(x) = 1-x^2
Step-by-step explanation:
The graph of f(x) is just shifted down 3 units
A shift down is a subtraction
f(x) = g(x) -3
= 4- x^2 -3
=1-x^2
Answer:
y = -2x+5
Step-by-step explanation:
y = -2x+1 is in the form y= mx+b where m is the slope and b is the y intercept
-2 is the slope
Parallel lines have the same slope so our new line will have the same slope
y = -2x+b
The point given is the y intercept (value when x is zero)
b = 5
y = -2x+5
