The total R value is computed from the R-values of the components in the stack as ...
(inches of wood)*(R-value of wood) +(inches of fiberglass)*(R-value of fiberglass) +(inches of foam)*(R-value of foam)
= (4 in)(2 /in) +(2 in)(4 /in) +(3 in)(5 /in)
= 8 +8 +15
= 31
The total R-value of the wall is 31.
Answer:

Step-by-step explanation:
An undefined slope means it is a vertical line, and every possible point at that line is at x = 3. y does not depend on x, and x cannot be anything other than 3, so the equation is just
