Answer:
The answer to your question is 7 units
Step-by-step explanation:
Data
A = (3, 7)
B = (-4, 7)
Process
1.- Write the formula of the distance between two points
dAB = [tex]\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}[/tex]
x1 = 3 y1 = 7 x2 = -4 y2 = 7
2.- Substitute the values
dAB = [tex]\sqrt{(-4 - 3)^{2}+ (7 - 7)^{2}}[/tex]
3.- Simplify
dAB = [tex]\sqrt{(-7)^{2} + (0)^{2}}[/tex]
dAB = [tex]\sqrt{49}[/tex]
4.- Result
dAB = 7 units
5.- Conclusion
The distance between these points is 7 units.
