Question

Tyree is determining the distance of a segment whose endpoints are A(–4, –2) and B(–7, –7).

Answer 1

Answer:

Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.

Step-by-step explanation:

to find the distance between two point A(-4, -2) and B(-7, -7) we use the following distance formula

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

x1=-4, x2=-7

y1=-2, y2=-7

so,

$d=\sqrt{(-7-(-4))^2+(-7-(-2) )^2\\}\\\\d=\sqrt{(-7+4)^2+(-7+2)^2 }\\\\d=\sqrt{(-3)^2+(-5)^2 }\\\\\\\\d=\sqrt{9+25}\\ \\d=\sqrt{34}$
