Timothy bought 10 cookies for $5.00. let x represent the number of cookies purchased, and let y represent the total cost. graph the line that represents the proportional relationship.

Number of cookies bought by Timothy for $ 5 = 10 cookies

→ $1  = 2 Cookies

Here, x = Number of cookies

$y = Total cost of cookies purchased

→10 x cookies = $ 5 y

→ x cookies = $

→ y = 2 x

So, Number of cookies and it's price represents equation of line in two variable in two dimensional coordinate system,  passing through origin.

Slope of line = 2, which represents that in $ 1 you get two cookies.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
