QUESTION 1

We want to find the length of the segment joining the points at (-1,6) and (-5,3).



We use the distance formula which is given by the formula,


d=√((x_2-x_1)^2+(y_2-y_1)^2)



d=√(( - 5 - - 1)^2+(3 - 6))^2)



d=√(( - 5 + 1)^2+(3 - 6)^2)




d=√(( - 4)^2+( - 3)^2)



d=√(16+9)



d=√(25)


d = 5 \: units


QUESTION 2

We want to find the length of the segment joining at (-4,1) and (3,7).




We use the distance formula to get,



d = \sqrt{(3 - - 4)^(2) + {(7 - 1)}^(2) }


d = \sqrt{(3 + 4)^(2) + {(7 - 1)}^(2) }





d = \sqrt{7^(2) + {6}^(2) }



d = √(49+ 36 ) .



d = √(85 ) \: units
