Question

The distance between points (3, 7) and (x1, y1) is the square root of (x1 - 3)2 + (y1 - 7)2. True or false?

Answer 1

The answer is True because the distance formula is √(x2-x1)²+(y2-y1)²

TRUE

Answer 2

Answer:

True

Step-by-step explanation:

By the distance formula,

The distance between two points $(a_1, b_1)$ and $(a_2, b_2)$ is,

$d=\sqrt{(a_2-a_1)^2+(b_2-b_1)^2}$

Here, $a_1=3$, $b_1=7$, $a_2=x_1$ and $b_2=y_1$

Thus, the distance would be,

$d=\sqrt{(x_1-3)^2+(y_1-7)^2}$

= the square root of $(x_1 - 3)^2 + (y_1 - 7)^2$
