point A is (-5,0). the distance between point a and point b is 5 units. the x-coordinate of point B is −2. what is one possible y-coordinate of point B?

Respuesta :

1 Calculate the distance between points A and B using the distance formula: √[(-2 - (-5))^2 + (y - 0)^2] = 5
2 Simplify the equation: √[3^2 + y^2] = 5
3 Square both sides: 3^2 + y^2 = 5^2
4 Solve for y: 9 + y^2 = 25
5 y^2 = 16, y = ±4
