Which expression could help you find the distance between (10,4) and (-6,4) ?
lina2011 [118]

Answer:

Option D. |10| + |-6|

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(10,4) and (-6,4)

substitute

d=\sqrt{(4-4)^{2}+(-6-10)^{2}}

d=\sqrt{(0)^{2}+(-16)^{2}}

d=16\ units

therefore

The expression that could help to find the distance is

|10| + |-6|=10+6=16\ units
