Answer:
Step-by-step explanation:
Point-slope formula is represented by the equation . When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the
,
, and
for real values.
The represents the slope of the line. Since we know the slope is -2, substitute -2 for
. The
and
represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for
and -6 for
. This gives the following answer and equation:

<span>So then R is 1/6 of the way from E to F.
The x distance from E to F is 11- 4=7.
So then the x distance from E is,
Similarly for y,
R:(31/6,22/3)</span>
