Explanation:</h2>
The Cartesian coordinate system is formed by two perpendicular axes, which are the x-axis and y-axis. In this problem, we are given two lines:

- The line
is parallel to the y-axis and has an undefined slope. - The line
is parallel to the x-axis and has a slope of zero.
Since the x and y-axes are perpendicular, then the lines
are also perpendicular.

Answer:
Mistake: -3-5=-2, -3-5=-8
Step-by-step explanation:
-3-(7x+5)+9x=-8+3x+10
-3-7x-5+9x=4x+2
-8+2x=4x+2
-8-2=4x-2x
-10=2x
-10/2=x
-5=x
