Answer:
The slope is -4/3
Step-by-step explanation:
The slope can be found from
m = (y2-y1)/(x2-x1)
= (-2-2 )/(6-3)
=-4/3
Answer:
80 miles
Step-by-step explanation:
The map scale compares the distance between two points on the map with the corresponding distance on the ground.
That is,
The formula makes it pretty easy to solve!
- map scale is <em>1 inch : 20 miles</em>
- distance on map is <em>4 inches</em>
- Let's say, the corresponding distance on the ground is <em>x miles.</em>
<em />
Substituting these values in the above mentioned formula:
<em>cross multiplying:</em>
<u>That makes the actual distance 80 miles!</u>
<u> </u>
<h3>ALTER</h3>
You can also use simple unitary method here:
1 inch on the map = 20 miles on the ground
∴ 4 inches on the map = 4 × 20 miles on the ground
<u>= 80 miles on the ground</u>
