Question

What is the distance between point R(-1, 7) and point T(-7, 7)?

O 1 unit
O 6 units
O 7 units
O 8 units

Answer 1

Answer: 6 units

Step-by-step explanation: first set up the distance formula

d= the square root of [(-7+1)^2+(7-7)^2}

the y values =0 so we are left with the square root of -6^2=d

and this simplifies out to d=6
