Answer:

B. False

Step-by-step explanation:

Given

Points: (x_7 - y_i),(4,8)

Required

Is the distance between them \sqrt{(x_7 - 8)^2 + (y_1 - 4)^2}

Given that there are two points, the distance between them is calculated using

Distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

In this case;

(x_1,y_1)= (x_7 - y_i)\\(x_2,y_2) =(4,8)

Substitute these in the given formula

Distance = \sqrt{(4- x_7)^2 + (8 - y_1)^2}

Comparing this with the given formula, both are not the same;

Hence, the formula is false and the correct formula is of the form \sqrt{(4- x_7)^2 + (8 - y_1)^2}
