576 I hope this help cause I did this two years ago so I'm a little rusty but I think this is correct
Answer:
48
Step-by-step explanation:
Here, the sides are in proportion.
⇒ 
⇒ 
⇒ k = 24 × 2
⇒ k = 48
To arrange the slopes we need to take their absolute values.
1. U<span>ndefined slope means a vertical line, so it is going to be steepest.
2.|4/3| = 4/3
3.|-3/2| = 3/2
4. 0 means horizontal line.
</span>From flattest to steepest: 0, -3/2, 4/3, undefined.
<span>6x + 10 = 4x -8
6x-4x = -8 - 10
2x = -18
x = -9
