Answer:
y = -4/3x -1
Step-by-step explanation:
y = slopex + y-int
We can find the slope -4/3 by going down 4 times to the level of the second point from the first point. Then we go to the right 3 times to get to the 2nd point.
y = -4/3x + b
The spot on the line where x is 0 will be the y-intercept
In this case it is -1
y = -4/3x - 1
To vertically strech a function, f(x) by a factor of c, that is cf(x)
so strech vertically by 2 means times whole thing by 2
so
2 times (4x^2-5) =8x^2-10
g(x)=8x^2-10

The volume of the pyramid with square base is:
V = s² * h / 3
s - the edge length, s = 5 cm
h - height, h = 7 cm
V = 5² * 7 / 3
V = 25 * 7 / 3
V = 58 cm³
