Answer:
y- intercept = - 2.5
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m = 
= 
= - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5
Answer:
Step-by-step explanation:
plug in 3 , 5 and 17 for n
8 + 3(3 -1) = 8 + 6 = 14
8 + 3(5-1) = 8 + 12 = 20
8 + 3(17-1) = 8 + 48 = 56
C= Cost
g= # of times games played
C = 0.50g + 3
C(0) = 0.50(0) + 3
C(0) = 0 + 3
C(0) = 3
This means that no games have been played yet and the entrance fee is $3
By using Pythagorean Theorem,
C^2= (10)^2+ (9)^2
C^2=100 + 81
C^2=181
C= 13.4cm
