X-axis that are 5 units from the point (4,-3), find the 2 missing coordinates?

Question

im confused... what is D (distance) equal to?

the answer is (0,0) and (8,0) but how do u get it?

Answer 1

distance = √(x1-x2)²+(y-y2)²

5 = √(x1-x2)²+(y1-y2)²

5 = √(x1-4)²+(y1--3)²

(x,0) is the point on x -axis

5 = √(x-4)²+(0+3)²

25 = (x-4)²+(0+3)²

25 = x²-8x+16 + 9

0 = x²-8x

0 = x(x-8)

x = 0 and 8

the answer is (0,0) and (8,0)
