Answer:
Slope: -3
Y intercept: (0, 9)
X intercept: (3, 0)
Step-by-step explanation:
In the equation y = mx + b, m is the slope and b is the y intercept.
Since the equation is y = -3x + 9, m is -3 and 9 is the y intercept.
So, the slope is -3 and the y intercept is at (0, 9)
To find the x intercept, plug in 0 as y and solve for x:
y = -3x + 9
0 = -3x + 9
-9 = -3x
3 = x
So, the x intercept is at (3, 0)

Answer:
The pet sitter babysat his dog for 3 hours.
Step-by-step explanation:
You know that a pet sitter charges $ 20 for supplies and $ 10 per hour of service, represented by the equation C = 10*n + 20, which describes the total cost she would charge for n hours of service.
The pet sitter charges a customer $ 50 for his service, so C has a value of $ 50.
Replacing:
50=10*n+20
Solving:
50 - 20= 10*n +20 -20
30= 10*n
30÷10= n
3= n
