Question

Use the distance formula to find The distance between the points (-1 ,3) and (2,6) write you answear as a square root, do not give me the decimal

Answer 1

Answer:

d = $3\sqrt{2}$

Step-by-step explanation:

The distance formula is d = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2} -y_{1} )^{2} }$

Plug in the points.

d = $\sqrt{(2-(-1))^{2}+(6 -3 )^{2} }$

Solve

d = $\sqrt{18}$

Simplify by separating 18 into 9x2

d = $\sqrt{9(2)}$

Take the square root of 9 to finish simplifying

d = $3\sqrt{2}$
