Question

Find the value of k so that the line 2x-3y=9 and kx-9y=18 will be parallel.

Answer 1

Answer:

In parallel the slope of line is equal.

Step-by-step explanation:

slope of line

-3y=9-2x

3y=2x-9

y= 2x/3- 3

y=mx+c

m= slope

slope = 2/3

slope of line 2

y = kx/9- 2

slope = k/9

slope of line = slope of line 2

2/3 = k/9

k= 9*2/3

k=18/3

k = 6
