Find the missing value so that the two points have a slope of 1/7 (7,2) and (0,y)

Mathematics

Answer:

y = 1

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to \frac{1}{7}

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (0, y)

m = \frac{y-2}{0-7}, that is

\frac{y-2}{-7} = \frac{1}{7} ( cross-  multiply )

7(y - 2) = - 7 ( divide both sides by 7 )

y - 2 = - 1 ( add 2 to both sides )

y = 1

1. Analyze the following pattern: 1, 2, 5, 10, 17,
valentinak56 [21]

Answer:

n² - 2n + 2

Step-by-step explanation:

The difference in the pattern are odd numbers.

2 - 1 = 1

5 - 2 = 3

10 - 5 = 5

17 - 10 = 7

So there is a -2n in the nth term.

If we subtract 1 on each term.

0, 1, 4, 9, 16

We get whole squares.

So there is a n² in the nth term.

(1)² - 2(1)+ c = 1

1 - 2 + c = 1

-1 + c = 1

c = 2

The nth term is:

n²-2n+2
