Answer 1

@Data_LG2

Answer 2

use the distance formula: \(\sf \Large PQ=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Answer 3

\(\sf Q(x_2, y_2)=(6,1)\\P(x_1,y_1)=(-3, 7)\)

Answer 4

\[\sqrt{(6-(-3)^{2}+ (1-7)^{2}}\] ? @Data_LG2

Answer 5

yes, then evaluate it and you'll get..?

Answer 6

\[\sqrt{81+-36}\]

Answer 7

then..?

Answer 8

just keep going, you're right :)

Answer 9

then i would get \[\sqrt{45}\] and after i find the square root of it?

Answer 10

yeah then round your answer to the nearest tenth
