Answer:
2x-5=y
I'm not sure how your graphing tool works so I'll give you five or so coordinates
(-1,-7)
(1,-3)
(0,-5)
(2,-1)
(-2,-9)
Step-by-step explanation:
You first need to write an equation that you can graph
Knowing that the slope is two we can write the following equation
2x+b=y
We also know that when x=1 y=-3
This gives us 2*1+b=-3
which means that 2+b=-3
subtract 2 from both sides to figure out the b=-3
This means that the line you have to graph is 2x-5=y
100/40×20.
100/40=2•5
2•5×20=50
the answer is 50
Each inch in the map is equivalent to 8 miles.
Explanation:
There is a distance of 24 miles between two parks. This 24 miles is represented by an 8-inch gap in the map.
So 8 inches on that particular map = 24 miles in real life.
To find the distance that an inch on the map represents we must divide both sides of the above equation. Since we need to calculate how much distance 1 inch represents we divide both the sides by 8 so that 8 inches on the map changes into 1 inch.
inches on the map =
miles between the two parks in real life,
1 inch on that particular map = 3 miles in real life.
So each inch on the given map is equal to 8 miles in real life.
