Answer:[tex]d=\sqrt{17}[/tex]
Step-by-step explanation: Since the distance formula is[tex]d=\sqrt{(x_{2}-x_{1 })^{2} + (y_{2} -y_{1})^{2}[/tex], You need to plug in the values. You'll then get[tex]d=\sqrt{(1-2)^2+(5-9)^2}[/tex]. (1-2) equals -1 and 5-9 equals -4.[tex]d=\sqrt{(-1)^2+(-4)^2}x^{2}[/tex] The next step is to solve the exponent.[tex]d=\sqrt{1+16}[/tex] Then you just need to simplify.
