Question 196300: National cost in billions of dollars for dental services can be modeled by the linear equation C=2.85n+30.52
a. find the C intercept for the line
b. find the n intercept for the line
c. graph the line for n ranging from 0 through 20 Answer by strickjh2005(4) (Show Source):
You can put this solution on YOUR website! Look at the basic linear equation; Y=mX+b
Your given equation is using different variables, but in a very similar form.
The slope is 2.85 and the y intercept is given as B (30.52).
If you go strait to C and graph the equation with the given information you can also find the x intercept (in this case n intercept).
Or you can do this algebraically, as long as you remember that the x intercept is going to be the number which makes Y=0.
C=2.85n+30.52
0=2.85n+30.52
2.85n=-30.52 by subtracting 30.52 from both sides.
n=-30.52/2.85 by dividing both sides by 2.85.
This value of approximately -10.70 is your n intercept.
