Answer:
The graph of the function for Science Buddies has a slope of 30
The graph of the function for Lab Thinkers has a slope of 25
The slope of each graph represents the monthly fee for each club
Step-by-step explanation:
Science Buddies
In this case, the slope represents the monthly fee because it represents the rate of change.
Slope= 30
Lab Thinkers
Slope= [tex]\frac{y2-y1}{x2-x1}[/tex]
Replace with the values on the table knowing that the x-values are independent and the y-values are dependent, months represent the x-values, and cost represents the y-values.
Use the points (1,45; 2,70)
[tex]\frac{70-45}{2-1}[/tex]
[tex]\frac{25}{1}[/tex]= 25
Slope= 25
The sign-up fee represents the y-intercept
The total cost is the result of the equation of the graph (the combination of your slope and the y-intercept)
Therefore, the monthly fee represents the slope
