If the point A(8,4) and B(-7,4) are located one the coordinate plane. Then the graph has been plotted and the distance between the points is 15 units
The first point = A(8,4)
The second point = B(-7,4)
Plot the point on the coordinate plane
The distance between the two points d = 
Where d is the distance between the two points
is the coordinates of the first point
is the coordinates of the second point
Substitute the values in the equation
The distance d = 
= 
= 15 units
Hence, If the point A(8,4) and B(-7,4) are located one the coordinate plane. Then the graph has been plotted and the distance between the points is 15 units
