Answer:
y=4x + 7
Step-by-step explanation:
Line=y=ax+b
b = where the line crosses the y-axis (where x=0). Here, it's 7.
a= vertical distance ÷ horizontal distance.
You can take any pair of distances to a point on the line, for example (4,1) is easy to read in the graph.
x=0 to 1 (horizontal distance=1-0=1)
and
y= 0 to 4 (vertical distance= 4-0=4)
a=4÷1=4.
So, the answer is y=4x + 7 as a= 4 and b=7.
Answer:
-13
Step-by-step explanation:
A. The cost per 20 boards is 3800. so each board costs 3800/20 or $190. So the cost equation is C(x) = 200 + 190x
B. Divide the cost function by x. C(x)/x = 200/x + 190
C. The graph will be a curve that starts at (1,390) and curves down and to the right. Your last point will be at (30, 200/30+190) Your asymptote will be the horizontal line at 190 because as x tends to infinity, the term 200/x goes to zero. (There is also a vertical asymptote at x = 0 because you can't divide by zero, but your graph won't include x=0)
D. The average cost tends to 190 which was your horizontal asymptote.
