1. so the scale factor between the two shapes 2/3 because 6 is 2/3 of 9
and 9 is 3/2 of 6. Therefore y would equal 6 also, x would equal 8, because 8 is 2/3 of 12, and z would equal 5 1/4.
Sorry but I don't know how to work out the second one.

Answer: see attached graph

<u>Step-by-step explanation:</u>

Choose values for t and plug them into the x equation and y equation to find the x,y coordinates.

Usually there is an interval provided. Since you did not specify an interval, I chose to use [-2, 2].

$\begin{array}{c||c|c||c}t&x&y&(x,y)\\-2&8&\frac{38}{5}=7.6&(8,7.6)\\\\-1&5&\frac{39}{5}=7.8&(5,7.8)\\\\0&4&\frac{40}{5}=8.0&(4,8.0)\\\\1&5&\frac{41}{5}=8.2&(5,8.2)\\\\2&8&\frac{42}{5}=8.4&(8,8.4)\end{array}$
