On a map's coordinate grid, Milton City is located at (-4,-3) and McDanielsville is located at(4, -9). How long is a train's route as the train travels along a straight line from Milton City to McDanielsville?

Given :

On a map's coordinate grid, Milton City is located at (-4,-3) and McDanielsville is located at(4, -9).

To Find :

How long is a train's route as the train travels along a straight line from Milton City to McDanielsville .

Solution :

We need to find the distance between points (-4,-3) and (4,-9) .

Now , distance between two points (x,y) and (a,b) is given by :

For points (-4,-3) and (4,-9) distance between them is :

Therefore , distance travelled by train is 10 units .

Hence , this is the required solution .

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
