Step-by-step explanation:

a) \\  \frac{a}{x - 1}  -  \frac{2}{x + 1}  =  \frac{4}{(x - 1)(x + 1)}  \\  \\  \frac{a(x + 1) - 2(x - 1)}{(x  -  1)(x + 1)} =  \frac{4}{(x - 1)(x + 1)}  \\  \\ a(x + 1) - 2x + 2 = 4 \\  \\ a(x + 1) = 4 + 2x - 2 \\  \\ a(x + 1) = 2x + 2 \\  \\ a (x + 1) = 2(x + 1) \\  \\ a= \frac{2(x + 1)}{(x + 1)}  \\  \\  \huge \red{ \boxed{a = 2}}

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 6) and (2, 0). a. Negative one-third c. 3 b.
statuscvo [17]

The slope of the line that passes through between (0, -6) and (2, 0) is: C. 3.

<h3>What is the Slope of a Line?</h3>

The slope of a line can be defined as the measure of the ratio of the vertical distance to the horizontal distance that exists between two points on a coordinate plane.

<h3>How to Find the Slope of a Line?</h3>

If we are given two points on a line, (x1, y1) and (x2, y2), the slope (m) is the rise/run = change in y / change in x = (y2 - y1)/(x2 - x1).

Given the following coordinates of two points as follows, (0, -6) and (2, 0), let:

(0, -6) = (x1, y1)

(2, 0) = (x2, y2)

Plug in the values into the slope formula to find the slope:

Slope (m) = (0 - (-6)) / (2 - 0)

Slope (m) = (0 + 6) / (2 - 0) [minus multiplied by minus is plus]

Slope (m) = (6) / (2)

Slope (m) = 3

Thus, the slope of the line that passes through between (0, negative 6) and (2, 0) is calculated as: C. 3.
