‼️10 points‼️ 1. Is the relationship shown by the data linear. If so, model the data with an equation.
A. The relationship is linear; y-5=-4/5(x-5).
B. The relationship is not linear.
C. The relationship is linear; y-5=5/4(x-1).
D. The relationship is linear; y-1=4/5(x-5).

C

Step-by-step explanation:

They values have a proportional relationship, as x increases by 4, y increases by five, giving a slope of 5/4. You can use the slope and a point given (I'll use (1,5)) in the equation y=mx+b to find the y-intercept, so solving for 5=5/4(1)+b you get 4.75 as your y-intercept. Simplified to slope intercept form y-5=5/4(x-1) is equal to our equation, so the answer is C.

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'.
