Question

Calculate the distance between the points J=(1,-2) and G=(9,-7) and in the coordinate plane. Give an exact answer (not a decimal approximation). I WILL GIVE 20) POINTS

Answer 1

|JG| = |(9, -7) -(1, -2)|

= |(9 -1, -7 -(-2))|

= |(8, -5)|

= √(8² +(-5)²)

= √(64 +25)

= √89

The distance between J and G is √89.
