Tom graphed the points A(2,-1) and B(3,4) on a coordinate plane.

FromTheMoon [43]

Answer:

AB = $\sqrt{34}$

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 2, 1) and (x₂, y₂ ) = B(3, 4)

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

= $\sqrt{5^2+3^2}$

= $\sqrt{25+9}$

= $\sqrt{34}$
