Lines AC and RC are not in the same plane and do not intersect.
They are called "skew lines."
Answer:

Explanation:
x-intercept → Plug in 0 for <em>y</em><em> </em>to get 4 for <em>x</em>
y-intercept → Plug in 0 for <em>x</em><em> </em>to get 8 for <em>y</em>

Answer:
Step-by-step explanation:
R = 9x + 8y
4 = 9x + 8*8
4 = 9x + 64
Subtract 64 from both sides
4 - 64 = 9x + 64 - 64
-60 = 9x
Divide both sides by 9
-60/9 = 9x/9
-20/3 = x
x = -6 2/3
