Question

Find the distance of AB if A is (-1, 0) and B is (2, -4). (Use distance formula)

Answer 1

5 units.

Explanation:

Formula:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

• d = distance
• x₂ = second x-value
• x₁ = first x-value
• y₂ = second y-value
• y₁ = first y-value

Calculations:

`d=√((2-(-1))^2+(-4-0)^2)\\d=√((3)^2+(-4)^2)\\d=√(9+16)\\d=√(25)\\d=5`
