Answer:

y = 30

Step-by-step explanation:

use distance formula:

(y-2)/(2--2) = 7

(y-2)/4 = 7

y-2 = 28

y= 30

Answer:

There are two values of y:

y = 2 + √33  or y ≈ 7.745

or

y = 2 - √33  or  y ≈ -3.745

Step-by-step explanation:

Use the Distance Formula to find the y-coordinate for the second point

  • (2, y)

The equation will progress into quadratic equation.  

  • Use Quadratic Formula or Completing the Square to solve for the value of y.
  • Since it is a quadratic equation, there is a maximum of two roots. Hence, two values of y.
