Answer: Part A= True, Part B= False, Part C= Line 1's slope is -2, Line 2's slope is 3, Part D: Line 1 is 3, Line 2 is 3, Part E; sorry I can't do that for you but use desmos if you need help, Part F: (0,3)

Step-by-step explanation:

Put the equations in slope-intercept form. This will help greatly. To check solutions, substitute x and y in. To graph lines, use the slope and y-intercept. Desmos graphing calculator is very helpful if you need help. Finding solutions, just find where the lines intersect. Good luck!

MA_775_DIABLO [31]

Answer: $A^{-1}=\left[\begin{array}{cc}\frac{3}{2}&-\frac{1}{2}\\-2&1\end{array}\right]$

Step-by-step explanation:

$\left[\begin{array}{cc}2&1\\4&3\end{array}\right]=\left[\begin{array}{cc}1&0\\0&1\end{array}\right]$

$\dfrac{1}{2}Row\ 1\rightarrow\left[\begin{array}{cc}1&\frac{1}{2}\\4&3\end{array}\right]=\left[\begin{array}{cc}\frac{1}{2}&0\\0&1\end{array}\right]$

$Row\ 2 -4 \ Row\ 1\rightarrow \left[\begin{array}{cc}1&\frac{1}{2}\\0&1\end{array}\right]=\left[\begin{array}{cc}\frac{1}{2}&0\\-2&1\end{array}\right]$

$Row\ 1-\dfrac{1}{2}\ Row\ 2 \rightarrow \left[\begin{array}{cc}1&0\\0&1\end{array}\right]=\left[\begin{array}{cc}\frac{3}{2}&-\frac{1}{2}\\-2&1\end{array}\right]$
