Question

Write a rule for the linear function in the graph.
Graph in comments..

Answer 1

That isn't correct. The slope should be positive @Chumpian

Answer 2

So C?

Answer 3

\[m=\frac{-1-3}{3-4}\]
gives the slope

Answer 4

i wanna say c

Answer 5

yes that sounds more likely
since the slope is positive and the y-intercept is definitely negative

Answer 6

if your distance from center mass to middle of side is 5 and its an equilateral triangle...

could you use a = r cos (180/n) to find the radius then
h^2 = a^2 + b^2
to find half the base length then double it to find the full base length then times that by double the apothem to find your vertical height and multiply out to find your area...?

Answer 7

a = r cos (180/n)
a = apothem
r = radius (to the corners
n = number of sides

so r = 10

Answer 8

so side length = 17.3
verticle height = 15
so area = 129.9

Answer 9

All that equals 130

Answer 10

y = 4x -13 correct!

Answer 11

Thanks everyone :)
