Find the slope of the line through points (4, 6) and (-6,2).
Pie

Answer: Slope = 2/5

Concept:

Here, we need to know how to find the slope.

Slope = (y₂ - y₁) / (x₂ - x₁)

If you are still confused, please refer to the attachment below for a clearer version of the formula

Solve:

<u>Given information</u>

(x₁, y₁) = (-6, 2)

(x₂, y₂) = (4, 6)

<u>Given formula</u>

Slope = (y₂ - y₁) / (x₂ - x₁)

<u>Substitute values into the formula</u>

Slope = (6 - 2) / (4 - (-6))

<u>Simplify values in the parentheses</u>

<u>REMEMBER to change [+, -] signs when there is a [-] sign in front</u>

Slope = 4 / (4 + 6)

Slope = 4 / 10

<u>Divide both numerator and denominator by 2 to get the simplest form</u>

Slope = (4 ÷ 2) / (10 ÷ 2)

Slope = 2/5

Hope this helps!! :)

Oksi-84 [34.3K]

Answer:

A and B ( page 12 and page 20 )

Step-by-step explanation:

1/4 of an hour he read 9 pages ( 15 mins ) ( 60 / 1 hour divided by 4 = 15 ) In other words 9 pages in 15 mins. To get to an hour u gotta multiply by 4. 15x4=60 9x4=36 ( 1 hour of reading is 36 pages read )

60 divided by 3 = 20

36 divided by 3 = 12 for sure it’s A and B
