Answer:


y - (-2) = (-5/3)\, (x - 6).

.Step-by-step explanation:

The
x-coordinates of the two given points are different. Therefore, the line that goes through these points would not be vertical. Likewise, this line would not be horizontal since the
y-coordinates of the given points are different.

If a line in a plane is of slope
m and goes through point
(x_(0),\, y_(0)), the point-slope equation of this line would be
y - y_(0) = m\, (x - x_(0)).

If a line in a plane goes through the points
(x_(0),\, y_(0)) and
(x_(1),\, y_(1)) (where
x_(0) \\e x_(1),) the slope of this line would be
m = (y_(1) - y_(0)) / (x_(1) - x_(0)).

Since the line in this question goes through points
(6,\, -2) and
(0,\, 8), the slope of this line would be:


\begin{aligned} m &= (8 - (-2))/(0 - 6) \\ &= (10)/((-6)) \\ &= -(5)/(3)\end{aligned}.

Let
(6,\, -2) be the point
(x_(0),\, y_(0)). The point-slope equation of this line would be:


y - (-2) = (-5 / 3)\, (x - 6).
