The equation of the line joining the points −2,4,2and 7,−2,5 is
x+23=y−4−2=z−11
x−2=y4=z2
x1=y−2=z5
x+25=y−42=z−17
The given points are −2,4,2and 7,−2,5
The direction ratios are 9,-6,3=3,-2,1
The equation of the line joining the pointsAx1,y1,z1,Bx2,y2,z2 isx−x1x2−x1=y−y1y2−y1=z−z1z2−z1
Therefore, the equation of the line joining the points −2,4,2and 7,−2,5is x+23=y−4−2=z−21
