30 I think because 6 12 18 24 30 and 10 20 30
Answer:
Slope - intercept form 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given points are ( -9 ,-8 ) and (-6,6)
slope of given two points

The equation of the straight line passing through the points and having slope


3 y + 2 4 = 14 x + 126
3 y = 14 x + 126 - 24
3 y = 14 x + 102


Slope - intercept form y= mx +C
Slope - intercept form 
it's 21/21 which would simplify to 1
How I got that answer was by multiplying 3/7 and 7/3 to get 21 both times
