Transform the equations into slope-intercep form:
Kx - 2y = 4 ––> y = [tex] \frac{K}{2} [/tex]x -2
x + 3y = 7 ––> y = [tex] \frac{-1}{3} [/tex]x + [tex] \frac{7}{3} [/tex]
For two equations to be parallel, their slope should be equal.
[tex] \frac{k}{2} [/tex] = [tex] \frac{-1}{3} [/tex]
k = -2/3
Kx - 2y = 4 ––> y = [tex] \frac{K}{2} [/tex]x -2
x + 3y = 7 ––> y = [tex] \frac{-1}{3} [/tex]x + [tex] \frac{7}{3} [/tex]
For two equations to be parallel, their slope should be equal.
[tex] \frac{k}{2} [/tex] = [tex] \frac{-1}{3} [/tex]
k = -2/3
kx-2y=4 --equation 1
x+3y=7 --equation 2
Transform each equation to y=mx+b; where m=slope
y=(kx)/2 -2 equation 3
y=-x/3 +7 equation 4
Since parallel lines have the same slope, we equate:
(kx)/2 =-x/3 multiplying both sides by 1/x
k/2 =-1/3
k=-2/3
Substitute k=-2/3 in equation 3
y=-x/3 -2
x+3y=7 --equation 2
Transform each equation to y=mx+b; where m=slope
y=(kx)/2 -2 equation 3
y=-x/3 +7 equation 4
Since parallel lines have the same slope, we equate:
(kx)/2 =-x/3 multiplying both sides by 1/x
k/2 =-1/3
k=-2/3
Substitute k=-2/3 in equation 3
y=-x/3 -2
