Answer:

Step-by-step explanation:

1. y - 4 = 1/2(x - 2)

y - 4 = 1/2x - 1

y = 1/2x + 3

2. y + 1 = -3/4(x + 8)

y + 1 = -3/4x - 6

y = -3/4x - 7

Answer:

109.375 cm³

Step-by-step explanation:

The volume of the cube is:

V = a³ = 5³ = 125 cm³

The volume of the cut prism:

V = Bh, B- area of the base, h- height

The base is a right triangle with legs of 2.5 each.

The volume is:

V = 1/2*2.5*2.5*5 = 15.625 cm³

Required volume of the solid is the difference of the above volumes:

125 - 15.625 = 109.375 cm³

This is a linear polynomials(or first degree polynomials). It is a form of y=ax+b.The line passes through (4, 5) and (2, 2), so we can build a dualistic equation:    ｛5=4k + b
   ｛2=2k + b
solve this equation, we can know that k=1.5 and b=-1, then the function is y=1.5x - 1, D is correct.
If y=1.5x - 1, then y-2=1.5x-1-2=1.5x-3=1.5(x-2), so A is correct, too.
y-4=1.5x-1-4=1.5x-5, so B is incorrect.
y-5=1.5x-1-5=1.5x-6=1.5(x-4), so C is correct.    Now we can know the answer: the correct options are A,C and D    Sorry my English expression is not very good, but hope it can help you:)
