Answer:

-4/19

Step-by-step explanation:

Here, we will use point-slop equation of the line to find the value of k

m = (y2 - y1)/(x2 - x1)

we can find the value of m using the points on the second line containing (5, -8) and (2,4)

m = (4 - (-8))/(2 - 5) = 12/(-3) = -4 -------------(i)

we will convert the first line equation into sloper intercept form

y = mx + c

0 = 19y - kx

19y = kx

y = kx/19

y = (k/19)*x

Here the m = k/19 and c = 0

Because the lines are parallel so their slop m would must be same.

Inserting the value of m of second line from the line (i)

-4 = k/19

k = -4/19
