So x=x
and y=pounds
when x=0, y=64
when x=1, y=63.1
to find slope, (y1-y2)/(x1-x2)=(64-63.1)/(0-1)=0.9/-1=-0.9=slope
y=-0.9x+b
subsitute
64=-0.9(0)+b
b=64
y=-0.9+64
so int 2001, x=11
y=-0.9(11)+64
y=-9.9+64
y=54.1

Answer:

$\left[\begin{array}{cc|c}1&0&2\\0&2&2\end{array}\right]$

Step-by-step explanation:

The system of equations can be written in standard form as ...

x + 0y = 2

0x +2y = 2

The augmented matrix representation of these is ...
