Answer:
The equation in slope intercept form for the total number of webpages for any number of weeks since the beginning of June 1997 is p=12w+200.
Step-by-step explanation:
Let p be the total number of webpages, w weeks since the beginning of June 1997.
It is given that at the beginning of June 1997 there were 200 webpages on the World Wide Web. The line passes through the point (0,200).
Fifty weeks later there were 260 webpages on the World Wide Web. It means the line passes through the point (5,260).
If a line passes through two points and
, then the equation of line is
The line passes through the points (0,200) and (5,260). So the equation of line
Add 200 on both sides.
Substitute y=p and x=w in the above equation.
Therefore the equation in slope intercept form for the total number of webpages for any number of weeks since the beginning of June 1997 is p=12w+200.
Answer:
The correct statement is:
- The slope of f(x) is same as the slope of g(x)
Step-by-step explanation:
- We see that the graph of the function f(x) is a line that passes through (0,2) and (1,-1)
Hence, the equation of the function f(x) is calculated by a two-point formula as:
( On comparing the equation of f(x) with slope intercept form.
i.e. y=mx+c
where m is the slope and c is the y-intercept)
We get slope of f(x)= -3
and y-intercept= 2
- The function g(x) is given by:
Hence, slope of g(x) = -3
and y-intercept= -6
Hence, we get that the slope of f(x) and g(x) is same.
( i.e. -3)
