What is the distance between -9 and 6 on the number line? Explain how you got your answer.

15

Step-by-step explanation:

Take the second number and subtract the first number

6 - ( -9)

6 + 9

15

The distance between the two numbers is 15

15

See two explanations below.

Step-by-step explanation:

The correct mathematical way to find the distance between two points on the number line, is to take the absolute value of the difference of the coordinates (numbers) of those points.

The distance between the points with coordinates a and b is |a - b|. If you do the subtraction in the other order, |b - a|, you get the same result.

Distance between -9 and 6 is:

|-9 - 6| = |-15| = 15

If you subtracted in the other order, you'd get the same result:

|6 - (-9)| = |6 + 9| = 15

As you can see, the distance is 15.

Now let's do it by just using logic and knowledge of the number line.

The point -9 is 9 units to the left of zero.

The point 6 is 6 units to the right of zero.

What is the distance from -9 to 6?

Start at -9 (9 units left of zero) and start moving toward 6. First you get to zero. It takes 9 units to go from -9 to 0. Now go from 0 to 6. It takes 6 units to go from zero to 6. Add the two distances, 9 + 6, and you get 15.

The distance from -9 to 6 on the number line is 15.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
