In order to find the distance between two point the formula used is:
PQ=√((x2−x1)^2+(y2−y1)^2)
or PQ=√((∆x)^2+(∆y)^2)
∆ is read as delta, or “change in” depending on its corresponding variable
Given points (-1,-4) and (2,2),
where x1 = -1, x2 = 2, y1 = -4, y2 = 2
PQ=√((2-(-1))^2+(2-(-4)^2)
PQ=√((2+1)^2+(2+4)^2)
PQ=√((3)^2+(6)^2)
PQ=√(9+36)
PQ=√(45)
The distance between two points is √45 or 6.71
