Mathematics: Explain how looking at a line can tell us whether its slope is negative, positive, undefined, or zero. Choose the correct answer below. O A. A line with a negative slope decreases from left to right, while a line with a positive slope increases from left to right. A line with a slope of zero is a vertical line, and a line with undefined slope is a horizontal line. O B. A line with a negative slope increases from left to right, while a line with a positive slope decreases from left to right. A line

The x coordinate is 2

Step-by-step explanation:

Given

A = (-2,5)

C = (6,-1)

Required

Determine the x coordinate of B

Since B is the bisector of AC, then B is the midpoint and will be calculated using;

$B(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})$

Considering the x coordinates alone;

$x = \frac{x_1 + x_2}{2}$

Where

(x_1,y_1) = (-2,5) and (x_2,y_2) = (6,-1)

Substitute values for x1 and x2

$x = \frac{-2 + 6}{2}$

$x = \frac{4}{2}$

x = 2

Hence;

The x coordinate is 2
