Use a table to solve the system of equations. If you use a calculator table, record the TbIStart and $\mathrm { V}_{TbI }$ entered. $$\begin{array} { l }
y - 2.8 x = 3.8 \
0.6 x + y = 0.4
\end{array}$$
A) (-1, 2)
B) (0, 1)
C) (-1, 0)
D) (-1, 1)
E) (0, 2)

To solve the system of equations using a table, we can first isolate $y$ in both equations to compare their values for different $x$. For the first equation, $y = 2.8x + 3.8$.For the second equation, $y = -0.6x + 0.4$.Setting them equal to each other to find the $x$ value where they intersect:$$2.8x + 3.8 = -0.6x + 0.4$$$$3.4x = -3.4$$$$x = -1$$Substitute $x = -1$ into one of the original equations to find $y$:$$y = 2.8(-1) + 3.8 = -2.8 + 3.8 = 1$$Therefore, the solution to the system of equations is $(-1, 1)$, which corresponds to choice D.
