Find the slope of the line that passes through the pair of points.<br><br> (–5.5, 6.1), (–2.5, 3.1)

hjlf

Slope of the line is -1.

Step-by-step explanation:

Given points are,

(-5.5,6.1),(-2.5,3.1)

Here,

$x_{1} = -5.5 ,\ \ \ x_{2}=-2.5\\y_{1} = 6.1,\ \ \ y_{2}=3.1$

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

Putting values;

$m=\frac{3.1-6.1}{-2.5-(-5.5)}\\m=\frac{-3}{-2.5+5.5}\\m=\frac{-3}{3}\\m=-1$

Slope of the line is -1.

An=2n-3 find the first five terms of the sequence

katen-ka-za [31]

Answer:

-1 , 1 , 3 , 5 , 7

Step-by-step explanation:

An = = 2n - 3

n = 1; A1 = 2*1 - 3 = 2 - 3 = -1

n =2; A2 = 2*2 - 3 = 4 - 3 = 1

n = 3; A3 = 2*3 - 3 = 6 - 3 = 3

n= 4; A4 = 2*4 - 3 = 8 - 3 = 5

n = 5; A5 = 2*5 - 3 = 10 - 3 = 7
