Answer:
the unknown, [?], has the value -18.
Step-by-step explanation:
Perform the indicated multiplication on the left side:
-14a - 18b = -14a + [?]b
Adding 14a to both sides, we eliminate a:
-18b = [?]b
Thus, the unknown, [?], has the value -18.
-18
Left Hand Side = -2(7a + 9b) = -14a - 18b
Comparing it with Right Hand Side, ? = -18
slope is -1
y1-y2/ x1-x2
= -3 - 7 / 8 - (-2)
= -10/ 10
= -1
the right one is b
because if you add all of the other oned it would be 24
