Find the length of the missing side

21.6 in

Step-by-step explanation:

since it's a right triangle, use the pythagorean theorem (a^2 + b^2 = c^2)

12^2 + 18^2 = c^2

144 + 324 = c^2

468 = c^2

c = square root of 468

c = 21.6333 (...) in

since you have to round it up to the nearest tenth, then the answer should be 21.6 in

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)
