Answer:
D. 20
Explanation:
To answer this question, we will use the distance formula which is as follows:
distance = [tex] \sqrt{(x2-x1)^2 + (y2-y1)^2} [/tex]
We are given:
point (-9,7) representing (x1,y1)
point (9,-2) representing (x2,y2)
Substitute with the givens in the above formula to get the distance as follows:
distance = [tex] \sqrt{(9--9)^2 + (-2-7)^2} [/tex] = 9√5 which is approximately 20 units
Hope this helps :)
