Answer:
Step-by-step explanation:
I assume that the three points given are the vertices of the triangle. So the three points are:
A (-4,1)
B (-7,5)
C (0,1)
The area of a triangle is given by:
where b is the base and h is the height.
Here we can take as follows:
- We can take the base to be the side AC, so that its length is equal to the distance between the two points:
- The height of the triangle is therefore the perpendicular distance between AC and point B. This is equivalent the difference in the x-coordinate between any point on AC and B, so:
Therefore, the area of the triangle is:
Answer:
(0,-2)
Step-by-step explanation:
First we find the equation of the line passes through and
.
The slope of the line is
So by the point slope formula the equation of the line is
When we have
.
Therefore the line joining the two points cuts the y-axis at (0,-2).
