Answer:
k = 3/4
Step-by-step explanation:
Parallel lines have the same slope so first, we need to find the slope of 8x + 6 = 2y. To do so, we can do the following:
8x + 6 = 2y
2y = 8x + 6
y = 4x + 3 (This is now in slope intercept form - y = mx + b where m = slope and b = y-int.)
Therefore, the slope is 4. Now, we can do:
3x = ky - 10
3x - 10 = ky
(3x / k) - (10 / k) = y
y = (3x / k) - (10 / k) (where k ≠ 0)
Now that the second line is in slope-intercept form, we can set the two x terms equal to each other, therefore:
3x / k = 4x
3x = 4x * k
3x / 4x = k
k = 3/4
