Answer:
15x + 14y = -18
Step-by-step explanation:
slope = (6 - -9)/(-8 - 6) = 15/-14
y = mx + b
6 = -15/14(-8) + b
6 = 60/7 + b
b = -18/7
y = -15/14x - 18/7
15/14x + y = -18/7, multiply everything by 14
15x + 14y = -18

<h3>
_</h3>
0.2 with the fraction bar over it because it keeps repeating.
Hope this helps, have a good day. c;
