PLS HELP WILL MAKE FIRST RIGHT ANSWER GETS BRAINLIEST ​

Answer 1

28. The choose E . y=-3/2x

29. The choose D. 4

A=(–2,–4) , B=(0,4)

m=(y2-y1)/(x2-x1)= (4-(-4)) / (0-(-2))=8/2=4

30. The choose E

(x+2)(x+4)=x²+4x+2x+8=x²+6x+8

I hope I helped you^_^

Answer 2

Answer:

E, D and E

Step-by-step explanation:

(28)

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate the slope using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = A (- 2, 3) and (x₂, y₂ ) = B (2, - 3) ← 2 points on the line

m = $\frac{-3-3}{2-(-2)}$ = $\frac{-6}{2+2}$ = $\frac{-6}{4}$ = - $\frac{3}{2}$

y = - $\frac{3}{2}$ x → E

(29)

Using the slope formula

with (x₁, y₁ ) = A (- 2, -4) and (x₂, y₂ ) = B (0, 4) ← 2 points on the line

m = $\frac{4-(-4)}{0-(-2)}$ = $\frac{4+4}{0+2}$ = $\frac{8}{2}$ = 4 → D

(30)

(x + 2)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 4) + 2(x + 4) ← distribute both parenthesis

= x² + 4x + 2x + 8 ← collect like terms

= x² + 6x + 8 → E
