Ответ:
The Option C shows the y-coordinate of the Point C: 7
The Point C is (-2,7)
Step-by-step explanation:
The area of a triangle can be calculated with this formula:
Where "b" is the base and "h" is the height.
We know that the segment AB, of 5 units long, is on the line , which is a horizontal line.
The point C is on the line , which is vertical.
Then we can say that:
Substituting the area and the lenght of the base into the formula and solving for "h", we get:
Then, the height (or the segment BC) of the triangle (Observe the figure attached) is 5 units long.
Therefore, the point C is: (-2,7)
And the y-coordinate of the point C is: 7
