Question

The coordinates of Point A are (-5,3). The coordinates of point B are (4,3). Which expression represents the distance, in units, between point A and point B

Answer 1

We would determine the distance between point A and B by applying the formula for determining the distance between two points which is expressed as

`\begin{gathered} \text{Distance = }\sqrt[]{(x2-x1)^2+(y2-y1)^2} \\ \text{From the information given, } \\ x1\text{ = - 5, y1 = 3} \\ x2\text{ = 4, y2 = 3} \\ \text{Distance = }\sqrt[]{(4--5)^2+(3-3)^2} \\ \text{Distance = }\sqrt[]{9^2+0^2} \\ \text{Distance = }\sqrt[]{81} \\ \text{Distance = 9 units} \end{gathered}`
