D.
slope = -3
passing thru(4,3)
y = mx + b
3 = -3(4) + b
b = 15
equation
y = -3x + 15
E.
(4,5)(6,9)
slope = (9-5)/(6-4) = 4/2 = 2
passing thru (4,5)(6,9)
y = mx + b
5 = 2(4) + b
b = -3
equation
y = 2x - 3
Answer:
The explanation of this question is given below in the explanation section
Step-by-step explanation:
The data is given in form of length and width.
Then, we need to convert it into improper fraction.
As you know that, the improper fraction is a fraction where the numerator (top number) is larger than the denominator (bottom number).
So, we converted it into improper fraction i.e.
Improper fraction= lenght/width
Then we reduce the fraction into lowest form and shown in ratio as depicted in attached picture with this solution.

9a + 5b + 5c = 9
Multiplying the whole equation by -2.
-18a - 10b - 10c = -18.
Hence, the answer is -18.
I believe 64x-8 is the correct answer.
