The points
and
are collinear because the slope of
equals the slope of
.
Solución
To show that the points
and
are collinear, we need to prove that the slope of the line segment
is equal to the slope of the line segment
.
The slope of a line segment can be calculated using the formula:
Let’s calculate the slope of the line segment
and the slope of the line segment
to see if they are equal.
Calculate the value by following steps:
Calculate the value by following steps:
- step0: Calculate:
- step1: Remove the parentheses:
- step2: Subtract the numbers:
- step3: Add the numbers:
- step4: Reduce the numbers:
- step5: Calculate:
The slope of the line segmentis -2.
Now, let’s calculate the slope of the line segment
.
Calculate the value by following steps:
Calculate the value by following steps:
- step0: Calculate:
- step1: Remove the parentheses:
- step2: Subtract the numbers:
- step3: Add the numbers:
- step4: Reduce the numbers:
- step5: Calculate:
The slope of the line segmentis also -2.
Since the slope of the line segment
is equal to the slope of the line segment
, the points
and
are collinear.

Bonus Knowledge
To show that points
,
, and
are collinear, we can verify if the area of the triangle formed by these points is zero. We use the formula for the area of a triangle given by the three points
,
, and
:
Substituting the coordinates of points
,
, and
:
Calculating step-by-step:
Now substituting these values back into the area equation:
Since the area is zero, points
,
, and
are indeed collinear.
