Question

Find the distance between the pair of points: (-9, -5) and (6, -5)​

Answer 1

Answer: 15

Explanation:

the equation to find the length of a line using the points given:

`√((x2-x1)^2+(y2-y1)^2)`

therefore you should understand which is y2, x2,y1 and x1

so you should always check which y value is bigger (the y value is the number in the right side of the point) so if the y value is bigger (y2) then eventually the value next to it which is x will always become x2 if the y value is big (y2)

so the other two values of the other point should become x1 and y1 since you already figured out the lager y value.

so now as for this question y2= -5, y1= -5, x2= 6 and x1= -9

now substitute these values to the equation I mentioned before ( you should make sure to remember the equation for sure as it is required when doing these types of questions)

`\sqrt{[6-(-9)]^(2) +[-5-(-5)]^2} \\\sqrt{(6+9)^2 + (-5+5)^2`

`√(15^2+0^2) \\√(225) \\15`(therefore 15 is the answer you have been looking for!)

I hope you understood and don't forget the equation which is the main help!

Answer 2

Answer:15

Step-by-step explanation: if your at -9,-5 you would be on the 3rd quadrant, and in order to get to 6,-5 (4th quadrant) you would just move to the right. you would only move right because the y-axis stays the same but the x-axis changes.
