Answer:

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = 4 and (a, b ) = (- 1, - 3 ) , then

y - (- 3) = 4(x - (- 1) ) , that is

y + 3 = 4(x + 1)

Serga [27]

Answer:

Step-by-step explanation:

To convert mixed number as improper fractions, use this rule:

$A\frac{B}C}=\frac{(A*C)+B}{C}$

<u>For Juan:</u> ( $4\frac{1}{6}$ )

$4\frac{1}{6}=\frac{(4*6)+1}{6}=\frac{25}{6}$

<u>For Antonio:</u> ( $3\frac{2}{3}$ )

$3\frac{2}{3}=\frac{(3*3)+2}{3}=\frac{11}{3}$

Answer choice A is correct.

krek1111 [17]

Answer:

$\large\boxed{A.\ -10x^2-33x+1}$

Step-by-step explanation:

$6x(x-4)-16x^2-(9x-1)\qquad\text{use the distributive property}\\\\=(6x)(x)+(6x)(-4)-16x^2-9x-(-1)\\\\=6x^2-24x-16x^2-9x+1\qquad\text{combine like terms}\\\\=(6x^2-16x^2)+(-24x-9x)+1\\\\=-10x^2-33x+1$
