Answer:
(x,y)=(-11,-19)
Step-by-step explanation:
Answer:
0y=x-10
Step-by-step explanation:
trust me i did all of it
<span>2a(-4b) + 3a(2a+6b)
= -8ab + 6a^2 + 18ab
= 10ab + 6a^2
6(6a - b) + 2a(b-3) / 2
= 36a - 6b + a(b-3)
= 36a - 6b + ab - 3a
= 33a - 6b +ab
-1/3 (12c-9d)
= -4c + 3d </span>
As x increases from 9 to 12 (a change of 3), y increases from -2 to 0 (a change of 2). Thus, the slope of this line is 2/3.
Subbing this info and the coordinates of one of the points into y = mx + b, we get:
-2 = (2/3)(9) + b. Solving for b: b = -2 -18/3 = -8. Then the equation of this line is:
y = (2/3)x - 8.
Check by subst.: Does (12,0) satisfy this equation? 0 = (2/3)(12) - 8? Yes.
