Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (3, 5, 0) and perpendicular to both i + j and j + k x(t), y(t), z(t) = The symmetric equations are given by −(x − 3) = y − 5 = z. x + 3 = −(y + 5), z = 0. x − 3 = y − 5 = −z. x + 3 = −(y + 5) = z. x − 3 = −(y − 5) = z.

Answer:(x-3)=-(y-5)=z

Step-by-step explanation:

Given

the point through which line passes is (3,5,0)

so we need a vector along the line to get the equation of line

It is given that line is perpendicular to both i+j & j+k

therefore their cross product will give us the vector perpendicular to both

v=(i+j)\times (j+k)=i-j+k

therefore we get direction vector of line so we can write

[tex]\frac{x-3}{1}=\frac{y-5}{-1} =\frac{z-0}{1}[/tex]=t

i.e.

x=t+3,y=-t+5,z=t

The parametric form of the equation is;

[tex]\rm x=x_1+at, \ x=3+1t, \ x=3+t\\\\y=y_1+at, \ y=5+(-1)t, \ y=5-t\\\\z=z_1+at, \ z=0+a(1), \ z=a[/tex]

The symmetric form of the equation is [tex]\rm x - 3 = -(y -5) = z[/tex].

Given

The line through (3, 5, 0) and perpendicular to both i + j and j + k

The symmetric form of the equation of the line is given by;

[tex]\rm \dfrac{x-x_1}{a}=\dfrac{y-y_1}{b}=\dfrac{z-z_1}{c}=t[/tex]

Where the value of [tex]\rm x_1=3, \ y_1=5\ and \ z_1=0[/tex].

To find a, b, c by evaluating the product of ( i + j) and ( j + k ).

[tex]\rm= (i+j)\times (j+k)\\\\= i-j+k[/tex]

The value of a = 1, b = -1 and c = 1.

Substitute all the values in the equation.

[tex]\rm \dfrac{x-x_1}{a}=\dfrac{y-y_1}{b}=\dfrac{z-z_1}{c}\\\\\dfrac{x-3}{1}=\dfrac{y-5}{-1}=\dfrac{z-0}{1}\\\\(x-3)=-(y-5)=z[/tex]

Therefore,

The parametric form of the equation is;

[tex]\rm x=x_1+at, \ x=3+1t, \ x=3+t\\\\y=y_1+at, \ y=5+(-1)t, \ y=5-t\\\\z=z_1+at, \ z=0+a(1), \ z=a[/tex]
