Answer:
-5xa^2-7a^3+7a^2+4
Step-by-step explanation:
If you know the slope and a point, the best option is to represent the line in the point-slope form which is:
(y-y1)=m(x-x1), where (x1,y1) is the point and m=slope
So try to isolate a by division and such
K=4a+9ab
we use reverse dstributive which is ab+ac=a(b+c) so
undistribute a
4a+9ab=a(4+9b)
k=a(4+9b)
divide both sides by (4+9b)

=a
a=
Answer:the answer is Y= -4/3x - 5/2
