That's an increase of 30,000,000 people in one year, a slope of 30 million and a good year for the internet.
If t is the year, and p is number of internet users,
p = 30000000(t - 1997) + 60000000
Answer: p = 30000000(t - 1997) + 60000000
As for linear versus exponential, one year of data can't really distinguish.
12.73 GB total when rounded to the nearest 100th.
3.5/27.5=y
y•100= 12.73
First of all, we know that it's a linear equation, which means it'll have to be y=mx+b.
Identify your points.
(0, 0) and (5, 4).
Now find the slope by doing
m = (y₂ - y₁)/(x₂ - x₁)
m = (4 - 0)/(5 - 0)
m = 4/5
So the slope is 4/5 or 0.8.
Now set the equation up. You have a point and the slope, so use the point-slope equation.
y - y₁ = m(x - x₁)
y - 4 = 4/5(x - 5)
y - 4 = 4/5x - 4
y = 4/5x
So the equation of the line is y=4/5x.
D. The slope is the same between any two points because it is linear.
If we add the 2 equations the terms in x dssappear and we get
2y = 1
so y = 1/2
Substitute in first equtaion:-
1/2 = - 1/2 x + 4
-1/2 x = 1/2 - 4 = - 7/2
x = -7/2 * -2 = 14/2 = 7
answer is (7, 1/2)
