basiclly, we look at the 2 points below and find the distance between them, then we match
d=[tex] \sqrt{( x_{2} -x_{1} )^{2}+( y_{2}-y_{1} )^{2}} [/tex]
when finding the distance between points (x1,y1) and (x2,y2)
if the x values, or y values are same, you don't need the distance formula, just use logic
(-10, 2) and (-2, 2)
the y value is the same so find the distance between the x values
from -10 to -2 is 8
8 matches with this one
(-3, -1) and (5, 1)
use distance formula
d=[tex] \sqrt{( 5-(-3) )^{2}+( 1-(-1) )^{2}} [/tex]=√68
(-3, -2) and (1, 3)
input
d=[tex] \sqrt{( 1-(-3) )^{2}+(3-(-2))^{2}} [/tex]=√41
(-3, -5) and (-2, -4)
input
d=[tex] \sqrt{( -2-(-3) )^{2}+( -4-(-5) )^{2}} [/tex]=√2
(0, 0) and (5, 5)
input
d=[tex] \sqrt{( 5-0 )^{2}+( 5-0 )^{2}} [/tex]=√50
(1, 2) and (1, -10)
x values are same so find distance between 2 and -10
answer is 12
(1, 2) and (5, 2)
y values are same
find distance between 1 and 5
answe ris 4
(2, 3) and (10, 9)
input
d=[tex] \sqrt{( 10-2 )^{2}+(9-3)^{2}} [/tex]=10
ANSWERS (because the spacing has gone wierd)
(-10, 2) and (-2, 2)=8
(-3, -1) and (5, 1)=√68
(-3, -2) and (1, 3)=√41
(-3, -5) and (-2, -4)=√2
(0, 0) and (5, 5)=√50
(1, 2) and (1, -10)=12
(1, 2) and (5, 2)=4
(2, 3) and (10, 9)=10
