![**Solve each system of equations by graphing on Desmos. Remember to draw a sketch of the graph with the point of intersection labeled.**
1.
\[
\begin{align*}
4x + 3y &= 28.6 \\
-2x - 4y &= -31.18
\end{align*}
\]
Solution: _______
2.
\[
\begin{align*}
3x - y &= -4 \\
3x - y &= -2
\end{align*}
\]
Solution: _______
3.
\[
\begin{align*}
y &= 2.5x - 12,000 \\
y &= 1.6x - 5,000
\end{align*}
\]
Solution: _______
**Instructions:**
Use Desmos or a graphing tool to plot each system of equations. Look for where the lines intersect to find the solution to each system. The solution represents the values of \(x\) and \(y\) at the intersection point. Be sure to label this point on your graph.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1af3ca9f-f26f-4df3-8cc5-e10bc90a82ff%2F55ffab80-439b-4f4f-a8f1-5f2dab8532b7%2F63zipqe_processed.jpeg&w=3840&q=75)
