To find ur sets of numbers, u simply plug in any number for x and solve for y
-x - 3y = -6.....lets say x = 0
-3y = -6
y = -6/-3
y = 2......so one set of pints is (0,2)
-x - 3y = -6...lets say x = 3
-3 - 3y = -6
-3y = -6 + 3
-3y = -3
y = -3/-3
y = 1....so another set of points is (3,1)
-x - 3y = -6.....,ets say x = 6
-6 - 3y = -6
- 3y = -6 + 6
-3y = 0
y = 0....and another point is (6,0)
so some points on ur line are : (0,2), (3,1), (6,0)
Since
for all
, you can write as a first step
Then for
, you can eliminate both factors of
in the numerator and denominator to end up with
.
Exact form
X= -1/2
Decimal form
X=-0.5

Answer:
y=1x+200
Step-by-step explanation:
Rewriting the function
The variable 'n' is the number of invitation ordered and $2.50 is the price for one invitation.
If we want to print 2 invitation, the expression 'n-2' becomes '2-2=0' which means the company will make 2.50(0) + 4.50 = 0 + 4.50 = $4.50 income (which is the fixed price)
To make profit, the company must receive order more than 2 invitation
