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

3. anonymous

So C?

4. freckles

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

5. anonymous

i wanna say c

6. freckles

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

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...?

a = r cos (180/n) a = apothem r = radius (to the corners n = number of sides so r = 10

9. anonymous

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

10. anonymous

All that equals 130

y = 4x -13 correct!
