let A is the point (-3,-1) and perpendicular intersect point on the x- axis is B
point B lies on x-axis so the coordinates of B are (-3,0)
now distance of the line AB is found out by distance formula:-
AB= root of (x2-x1)^2+(y2-y1)^2
AB= root of(-3+3)^2+(0+1)^2
AB= root of (0)^2+(1)^2
AB=root of 0+1
AB= root of 1
AB=1 unit (Answer)
