Using proportions, it is found that $147.8 billion was spent on television advertising in the previous year.
- $x, in billions, was spent on advertising expenditures on television last year.
- This year, the amount declined 4.1%, hence it is 100% - 4.1% = 95.9% of last year's amount, that is, 0.959x.
This year spending's is of 141.7 billion, hence, the equation is:

Answer:
y = 2x + 2 
Step-by-step explanation:
The general form
is;
y = mx + b
where m is the slope and b is the y-intercept 
so we have;
y = mx + 2
To get m, substitute the point (-1,0)
So we have 
0 = -m + 2
m = 2
So the equation is;
y = 2x + 2
