The slope-intercept form:

y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

m - slope

b - y-intercept

We have the points (-1, 5) and (1, -1). Substitute:

m=\dfrac{-1-5}{1-(-1)}=\dfrac{-6}{2}=-3

y=-3x+b

Put  the coordinates of the point (1, -1) to the equation of the function:

-1=-3(1)+b\\-1=-3+b\qquad|\text{add 3 to both sides}\\\\2=b\to b=2

<h3>Answer: y = -3x + 2</h3>

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

m=(-1-5)/(1--1)

m=-6/2

m=-3

y-y1=m(x-x1)  point slope form

y-5 = -3 (x--1)

y-5 = -3 (x+1)

distribute

y-5 = -3x -3

add 5 to each side

y = -3x+2

Answer:

The answer to your question is:

Step-by-step explanation:

   \frac{x^{2}-16 }{2x + 4} \frac{x^{3}-2x^{2} + x }{x^{2}+ 3x - 4}

Factorize    \frac{(x+4)(x-4)}{2(x+2)}  \frac{x(x^{2}-2x + 1) }{(x+4)(x-1)}

Factorize    \frac{(x+4)(x-4)}{2(x+2)} \frac{x(x-1)^{2} }{(x+4)(x-1)}

Simplify      \frac{x(x-4)}{2(x+2)}

Here is a sales tax of $9 on an item that costs $120 before tax. the sales tax on a second item is $19.05. how much does the sec
Annette [7]
% of sales tax = 9/120 x 100 = 900/120 = 7.5%

Let the cost of the second item be x, then 7.5/100 x = 19.05
0.075x = 19.05
x = 19.05/0.075 = 254.

Therefore, the cost f the second item is $254
