What is the slope of a line that passes through the points (4,2) and (2, -8)

5

Step-by-step explanation:

Slope equation is y2-y1/x2-x1

Insert into equation: -8-2/2-4

simplify: -10/-2

negatives cancel out because there is one on top and one on bottom: 10/2

simplify further: 10/2=5

- 1 /3

Step-by-step explanation:

The formula for finding the slope of a line is: Where ( x 1 , y 1) and( x2,y2)are two points on the line. Substituting the values from the points in the problem gives M= 4-2/-2-4=2/-6 and when you simplify it, it comes out to -1/3

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
