It looks like you've shared a system of equations that need to be solved by graphing. I'll start by solving the first system for part (a):

a) Solve the system:

$y = x - 5$ $y = 3 - x$

To solve this by graphing, we can rewrite the equations as lines and find where they intersect.

1. The first equation $y = x - 5$ is in slope-intercept form. The slope is 1, and the y-intercept is -5.
2. The second equation $y = 3 - x$ can be rewritten as $y = -x + 3$, with a slope of -1 and a y-intercept of 3.

To graph these:

• For $y = x - 5$, start at (0, -5) and use the slope of 1 to plot the next points (1, -4), (2, -3), etc.
• For $y = -x + 3$, start at (0, 3) and use the slope of -1 to plot the points (1, 2), (2, 1), etc.

These lines will intersect at the point where both equations are satisfied.

Let me know if you'd like the detailed steps for plotting or if you want me to proceed with the other parts!
