- to find x intercept put y=0 and z=0. we get x=9. This can be written as (9,0,0)
to find z intercept put x=0 and y=0. we get z=-6. This can be written as (0,0,-6)
nw find d distance btwn these 2 points.. i.e sqrt((x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2)...sqrt[ 9^2 + 0 + (-6)^2 ]=sqrt 117 = 10.8166 ~ 10.82 - 11 years agoHelpfull: Yes(37) No(0)
