Answer:
y = - x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 8x - 4y = 12 into this form
Subtract 4x from both sides
- 4y = - 8x + 12 ( divide all terms by - 4 )
y = 2x - 3 ← in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
Since the line passes through the origin then c = 0
y = - x ← equation of perpendicular line
Answer:
$677.18
Step-by-step explanation:
Data provided in the question:
Bill’s nominal income in 1990 = $1,009 per month
CPI value in the year 1990 = 149
CPI value in the year 2017 = 192
Now,
The Consumer price index ( CPI ) is given as :
CPI =
thus,
for the given case of year 1990
149 =
or
Real income in 1990 =
or
Real income in 1990 = $677.18
