Question 158648This question is from textbook college algebra
: The total world consumption of oil increased from 68.200 million barrels per day in 1995 to 73.215 million barrels per day in 1999. Create a linear model involving a relation between the year and the daily oil consumption in that year. Let t =0 represent the year 1995.
Can someone help me with this problem? Thanks Matt This question is from textbook college algebra

The total world consumption of oil increased from 68.200 million barrels per day in 1995 to 73.215 million barrels per day in 1999. Create a linear model involving a relation between the year and the daily oil consumption in that year. Let t =0 represent the year 1995
:
Using the given information, assign the x,y values as follows:
x1 = 0 (1995); y1 = 68.2 (million)
x2 = 4 (1999); y2 = 73.215 (million)
;
Find the slope (m); m = %28y2-y1%29%2F%28x2-x1%29
m = %2873.215+-+68.2%29%2F%284-0%29 = 5.015%2F4 = 1.25375
:
Create an equation using the point/slope formula: y - y1 - m(x - x1)
:
y - 68.2 = 1.25375(x - 0)
:
y = 1.25375x + 68.2; is the equation
