Answer:
-1
Step-by-step explanation:
The slope formula is useful:
m = (y2 -y1)/(x2 -x1)
m = (2 -4)/(0 -(-2)) = -2/2 = -1
The slope of this line is -1.
_____
The points on the line drop 1 unit for each 1 unit to the right.
m = rise/run = -1/1 = -1
<u>ANSWER</u>
B. (5.75, 0)
<u>EXPLANATION</u>
If the point P(x,y) partitioned
and
in the ratio m:n, then
If the coordinates are A(−4,12) and B(9,−4), then:
The correct choice is
Given:
To find:
The quadrant in which lie.
Solution:
Quadrant concept:
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II, only and
are positive.
In Quadrant III, only and
are positive.
In Quadrant IV, only and
are positive.
We have,
Here, is negative and
is also negative. It is possible, if
lies in the Quadrant IV.
Therefore, the correct option is D.
