4x+4y=-9
first change into yintercept form
y=-x-9/4
to find yintercept let x=0
y=-0-9/4
y=-9/4 or -2.25
to find xintercept let y=0
0=-x-9/4
x=-9/4
so the x and y coordinates are -2.25 and -2.25 respectively
Pretty simple question, just set up the equation.
A) say Thad is right then equation is as follows:
X * 0.002 = 12.37
Where X is monthly income.
So to solve for X just divide 12.37 by 0.002 (0.2%)
6185$ per month. Which no offense to Thad, but means he’s probably some kind of software engineer or investment banker if he’s making that much a month. (Unlikely for Thad)
B) if he’s wrong then just set up again
X * 0.02 = 12.37
Where x = monthly income
So x= $618.5
More likely given he’s complaining about a 12$ lunch when inflation has the yelp one ($) sign restaurants charging 15 or 16 just for a meal with tip and tax.
Anyways my rant aside hope this helps.
