Points] SCALCET7 12.5.015. (a) Find symmetric equations for the line that passes through the point

(4,-5,8)

and is parallel to the vector

(:-1,4,-2:)

.

(x+4)/(-1)=(y-5)/(4)=(z+8)/(-2)

(x-4)/(-1)=(y+5)/(4)=(z-8)/(-2)

.

x+4=(y+5)/(4)=(z-8)/(-2)

.

-(x+4)=4(y-5)=-2(z+8)

.

-(x-4)=4(y+5)=-2(z-8)

. (b) Find the points in which the required line in part (a) intersects the coordinate planes. point of intersection with

xy

-plane point of intersection with

yz

-plane point of intersection with

xz
