Answer:
Option b Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
[tex]A(-4,-2)\\B(-7,-7)[/tex]
step 1
substitute the values in the formula
[tex]d=\sqrt{(-7-(-2))^{2}+(-7-(-4))^{2}}[/tex]
step 2
Simplify
[tex]d=\sqrt{(-7+2)^{2}+(-7+4)^{2}}[/tex]
step 3
[tex]d=\sqrt{(-5)^{2}+(-3)^{2}}[/tex]
step 4
[tex]d=\sqrt{25+9}[/tex]
step 5
[tex]d=\sqrt{34}[/tex]
therefore
Tyree’s solution is inaccurate. In step 1, he substituted incorrectly.
