Y = -x+1 is in the form y=mx+b. To compare their slopes, let's get x+y=1 into y=mx+b form.
x+y=1
-x -x
-----------
y=-x +1
Both functions have a slope of -1, and both have the y-intercept of 1.
Since they are the same line, they will be on top of each other and have infinitely many solutions.
Answer:
if the interest rate is 4.5% for 6 months (not per annum) then the answer is $45 is the interest he have to pay.

Answer:
1. The supply equation is y=10x-50
2. the demand equation is y=-10x+700
3. The solution for the system of equations is (75/2,325). This means That the demand and supply will be the same when the price is 37.50$
4. Write the x-coordinates in 10's and y-coordinates in 100's. Put 2 points for supply as (10,50) and (20,150) and connect them. For demand, put 2 points as (10,600) and (20,500) then connect the 2 points.
5. A) The equilibrium point is (75/2,325)
B) this compares because you can solve a system of equations by graphing or substituting.
