Help 10 pts!! For a project on Egypt, Nick is building a paper model of a square based pyramid. The square base measures 8 inches by 8 inches.
The height is 9.2 inches. If Nick carves a piece of foam to place inside the pyramid for support, which measurement BEST describes
the amount of foam used? (round to nearest whole number)
A)
196 in?
B)
224 in?
C)
196 in?
D)
224 in?

C. 196 in3

No explanation needed

y = (-9/8)x + 7

Step-by-step explanation:

the line equation for slope intercert form looks like this

y = mx + b

m is the slope

b is the y intercept

The line intercepts the y at b= 7 (as noted in point (0, 7)

To find slope, use the 2 points given and the slope formula

m = (y2 - y1) / (x2-x1)

point (x1, y1) is  (0, 7) and

point (x2, y2) is (8, -2)

plug in the correct spots for m = (y2 - y1) / (x2-x1)

m = (-2 - 7) / (8 - 0) = -9 / 8

substitute y = mx +b = (-9/8)x + 7

I hope this helps :-)
