What is the image point of (–7, 1) after a translation left 4 units and down 5 units?
1 answer:
<h2>Translating a Point</h2><h3>Answer:</h3>
When we first translate the point to the left by
units, we just need to subtract the
-coordinate of the point by
.
Now we have the point . We then translate it down by
units by subtracting the
-coordinate of the point by
units.

The area of the triangle can be calculated using the distance formula if the coordinates are given.
<h3>What is the triangle?</h3>The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle with coordinates on the coordinate plane.
It is required to find the area of the triangle using the coordinate points.
Here the coordinates are not given, so we are assuming the coordinates are (x1, y1), (x2, y2), (0,0)
From the distance formula:
The distance(b) between (0, 0) and (x1, y1):
The distance between (0, 0) and (x2, y2):
So the area of the triangle:
A = bh/2
Thus, the area of the triangle can be calculated using the distance formula if the coordinates are given.
