A) If the year 1997 is year x=1, then 1996 is year x = 0.
Add 4 to 1996 to get year x = 4
1996 + 4 = 2000
B) I assume you mean 2018. Subtract 1996, which is year x = 0
2018 - 1996 = 22
So 2018 is year x = 22
C,D) The equation is in the form y = mx + b.
y = 0.l5 x + 0.79
y = mx + b
m = 0.15
b = 0.79
m is the slope, and b is the y intercept.
The linear equation
y=0.15x+0.79
represents an estimate of the average cost of gas for year x starting in 1997. the year 1997 would be represented by x=1, for example, as it is the first year in the study. similarly, 2005 would be year 9, or x=9
A) what year would be represented by x=4?
B) what x-value represent the year 20018?
C) what is the slope (or rate of change) of this equation?
D) what is the y-intercept?
