Answer:
x = -4 , 4
Step-by-step explanation:
The point (x,4) is equidistant from (0,1) and line y=-1
y=-1, it is horizontal line.
Let point on line be (x,-1)
Distance formula: ![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Distance between (x,4) and (x,-1) = Distance between (x,4) and (0,1)
![\sqrt{(x-x)^2+(4+1)^2}=\sqrt{(x-0)^2+(4-1)^2](https://tex.z-dn.net/?f=%5Csqrt%7B%28x-x%29%5E2%2B%284%2B1%29%5E2%7D%3D%5Csqrt%7B%28x-0%29%5E2%2B%284-1%29%5E2)
![\sqrt{5^2}=\sqrt{x^2+3^2](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E2%7D%3D%5Csqrt%7Bx%5E2%2B3%5E2)
![25=x^2+9](https://tex.z-dn.net/?f=25%3Dx%5E2%2B9)
![x^2=16](https://tex.z-dn.net/?f=x%5E2%3D16)
![x=\pm \sqrt{16}](https://tex.z-dn.net/?f=x%3D%5Cpm%20%5Csqrt%7B16%7D)
![x=\pm 4](https://tex.z-dn.net/?f=x%3D%5Cpm%204)
hence, the value of x is 4 and -4
