Write in slope-intercept form an equation of the line that passes through the points (−1,12) and (1,2).

zzz [600]

Answer:

$y=-5x+7$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

the points (−1,12) and (1,2)

substitute

$m=\frac{2-12}{1+1}$

$m=\frac{-10}{2}$

$m=-5$

step 2

we know that

The equation of the line in slope intercept form is equl to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=-5$

$point\ (1,2)$

substitute in the linear equation and solve for b

$2=-5(1)+b$

$b=2+5=7$

therefore

$y=-5x+7$

In triangle ABC, a = 3, b = 5, and c = 7. Find the approximate value of angle A.

Lady bird [3.3K]

Answer:

21.8° (22° to the nearest degree)

Step-by-step explanation:

Using cosine law:

a² = b² + c² - 2bc(cosA)

3² = 5² + 7² - 2(5)(7)cosA

cosA = 13/14

A = 21.7867893

Approximately angle: 22°
