QUESTION 5 for Gradescope: The lines 3x+y=0 and x+y=-2 intersect at the point (1,-3). Provide equations for TWO more geometrically distinct* lines which also pass through (1,-3). (*”Geometrically distinct” means that the lines do not overlap when plotted.)

QUESTION 1 for Gradescope Find the solution to the following system of linear equations using the method of substitution. Show your work. {2x+2y=10x+2y=7{“version”:”1.1″,”math”:”\begin{cases} 2x+2y& =10\\ x+2y & = 7 \end{cases}”}

QUESTION 6 for Gradescope: The following system of equations is converted to an augmented matrix and row reduced using the row operations shown below. {◼x+◼y+◼z=◼(equation of purple plane)◼x+◼y+◼z=◼(equation of blue plane)◼x+◼y+◼z=◼(equation of green plane){“version”:”1.1″,”math”:”\begin{cases} \blacksquare x + \blacksquare y + \blacksquare z & = \blacksquare \hspace{2 mm} \text{(equation of $\textcolor{magenta}{purple}$ plane)}\\ \blacksquare x + \blacksquare y + \blacksquare z & = \blacksquare \hspace{2 mm} \text{(equation of $\textcolor{blue}{blue}$ plane)}\\ \blacksquare x + \blacksquare y + \blacksquare z & = \blacksquare \hspace{2 mm} \text{(equation of $\textcolor{green}{green}$ plane)}\end{cases}”}Note: the coefficients of the system and the entries of each augmented matrix have been intentionally omitted. The row operations are labeled A-E. Determine which row operation(s) correspond(s) to a visual/geometric change in the plotted system. You DO NOT need to plot the lines, i.e., no illustrations are necessary here. But be clear about which color(s) line(s) are affected at each step.

The Unit Two Exam will be available from Monday, July 7th at 12:01am to Saturday, July 12th at 11:59pm. You can complete the exam at any point during this window. Failure to complete the exam will result in an automatic zero with absolutely no makeups; regardless of your excuse. Each student will be responding to 50 questions that can be one of the following: multiple choice, true/false, or matching. Each student will be given sixty minutes to complete the exam and they must complete it in one session (once you start the exam, the timer will begin and will automatically submit once time expires). The exam is not open note. Students are required to use HonorLock for this exam.
