Question

Find the value of y ,if the distance between the points (2,y) and (-4,3) is 10, can u pls explain in detail

Answer 1

Answer:

11, -5

Step-by-step explanation:

10 = √[2-(-4)]²+(y-3)²

100 = (2+4)² + (y-3)²

100 = 36 + (y²-6y+9)

55 = y²-6y

y² - 6y - 55 = 0

y² - 11y + 5y - 55 = 0

y(y-11) + 5(y-11) = 0

(y-11) (y+5) = 0

Therefore, y = 11,-5
