x is time and y is pencils that you have
'starts with 90' so at x=0, plot y=90
'gives away 15 every hour' so for every 1 hour, move 15 down on y
so at x=1, do 90-15=75 pencils
at x=2, do 75-15=60 pencils
etc
until you get to
x=6, do 15-15=0 pencils then stop because you can't give away 15 pencils when you have 0
see attachment for plot
I don't know how your segment tool works so you do it
if it draws a line, you only need 2 points, just do when x=0, y=90 and when x=6, y=0

<em>Complete Question:</em>
<em>Katya creates handmade sets of dolls, which is sold to craft and souvenir stores. The first set of dolls has a middle diameter of 7cm and a height of 12cm.</em>
<em>Katya made another set of dolls. In the new set, the largest doll has a diameter of 8.75 cm and a height of 15.6 cm. Is this a dilation of the first set of dolls? </em>
<em></em>
Answer:
The new set is not a dilation of the first set
Step-by-step explanation:
Given
First Set:
New Set:
Required
Determine if the new set is a dilation of the second
To do this, we pass through the following steps:
1. Divide the height of the first set by the new set
2. Divide the diameter of the first set by the new set
3. Result in (1) and (2) must be equal if the new set is a dilation of the first set
Following the steps above:
(1)
(2)
(3) Make comparison
The ratio in (1) does not equal the ratio in (2)
i.e.
<em>Hence, the new set is not a dilation of the first set</em>
