Given that point a (- 5,0) B (3,0) point C is on the Y axis, and the area of triangle ABC is 12, the coordinate of point C is?

Given that point a (- 5,0) B (3,0) point C is on the Y axis, and the area of triangle ABC is 12, the coordinate of point C is?

AB is all on the x-axis
Then the bottom AB = | - 5-3 | = 8
High is the distance from C to AB, that is, to the x-axis
The area is 12
So the height is 12 × 2 △ 8 = 3
So the absolute value of C is 3
C is on the y-axis
So C (0, - 3) or (0,3)
