Question

What is the distance between (2,9) and (1,5)

Answer 1

Answer:$d=\sqrt{17}$

Step-by-step explanation: Since the distance formula is$d=\sqrt{(x_{2}-x_{1 })^{2} + (y_{2} -y_{1})^{2}$, You need to plug in the values. You'll then get$d=\sqrt{(1-2)^2+(5-9)^2}$. (1-2) equals -1 and 5-9 equals -4.$d=\sqrt{(-1)^2+(-4)^2}x^{2}$ The next step is to solve the exponent.$d=\sqrt{1+16}$ Then you just need to simplify.
