Answer:
<h2>Slope = 8</h2><h2>y-intercept = - 9</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question we have the equation as y = 8x - 9
Comparing with the original equation
y = mx + c
Slope(m) = 8
y-intercept(c) = - 9
Hope this helps you
Answer:
C(r) = 5 + 2.5r
Step-by-step explanation:
An amusement park charges a fee of 5$ each time you enter the park. The cost of each ride is $2.50.
Therefore, the cost of r number of rides inside the park will be $2.5r.
