Question

Points C(5, 7) and D(–3, –12) are on a line. What is the run from point D to point C?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

point C (5 , 7)

point D (-3 , -12)

Step 02:

distance between two points:

`d\text{ = }\sqrt{(x2-x1)\placeholder{⬚}^2+(y2-y1)\placeholder{⬚}^2}`
`d\text{ =}\sqrt{(-3-5)\placeholder{⬚}^2+(-12-7)\placeholder{⬚}^2}=\sqrt{(-8)\placeholder{⬚}^2+(-19)\placeholder{⬚}^2}`
`d=√(64+361)=√(425)=20.62`

The answer is:

distance between C and D:

20.62
