GUYS PLEASE PLEASE HELP ME

5 units.

Step-by-step explanation:

Use the following equation:

distance (d) = √((x₂ - x₁)² +  (y₂ - y₁)²)

Let:

(x₁ , y₁) = (5 , -1)

(x₂ , y₂) = (9 , 2)

Plug in the corresponding numbers to the corresponding variables:

d = √((9 - 5)² +  (2 - (-1))²)

d = √((4)² + (2 + 1)²)

d = √((16) + (3)²)

d = √(16 + 9)

d = √(25)

d = 5

Your distance between points (9 , 2) & (5, -1) is 5 units.

i dont know sorry

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3
