Answer:
slope (m)= y2-y1 /x2 -x1
Step-by-step explanation:
or m= ((9-5)/ (5-3)
or,m= 4/2
or,m =2
Answer:
line
Step-by-step explanation:
Given:
Sum of interior angle
To find:
Number of sides of a polygon
Solution:
Using sum of interior angles formula:

where "S" is the sum of interior angels and "n" is the number of sides of a polygon.
Divide by 180° on both sides.

Cancel common factor 180°.

Add 2 on both sides.


Switch the sides.

Therefore number of sides of a polygon is
.
Answer:
1 cm=8 km
Step-by-step explanation:
We can use a ratio to determine the scale. Take the distance on the map on the left and the "real distance" on the right
6 cm=48 km
Divide by 6
6 cm/ 6 = 48 km /6
1 cm=8 km
