____________________________________________________________

Distance between two points can be found by the distance formula i.e.

√ (x₂ - x₁)² + (y₂ - y₁)² 

x₁ = 8, x₂ = -7, y₁ = -9, y₂ = 4

According to the question, let's put the values

√ (-7 -8)² + (4 + 9)²

√ (-15 )² + (13)²

√ 225 + 169

√394

19.849 units approx

Answer 2

Hey !!

Here's your answer.. ⬇⬇

Distance formula :- √( x2 - x1 )^2 + ( y2 - y1 )^2

x1 = 8 y1 = ( -9 )
x2 = ( -7 ) y2 = 4

Distance between ( 8, -9 ) and ( -7, 4 ) =

= √ ( - 7 - 8 )^2 + ( 4 - ( - 9 )^2 )

= √ ( - 15 )^2 + ( 13 )^2

= √ 225 + 169

= √ 394

= 19.85

Distance between ( 8, -9 ) and ( -7, 4 ) is 19.85 approx.

HOPE IT HELPS..
