Artyom0805 [142]

Answer:

c

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (2, 3)

m = \frac{3+3}{2+8} = \frac{6}{10} = \frac{3}{5} → c

Solve the equation for a.
katrin [286]

Answer:

a= \frac{k}{9b+4}

Step-by-step explanation:

In this question, you would solve for "a".

Solve:

K = 4a + 9ab

Since we have our "a" on the same side, we can factor it out from the variables:

K = a(9b + 4)

To get "a" by itself, we would have to divide both sides by 9b + 4:

K/9b+ 4 = a

Your answer would be K/9b+ 4 = a

It would look like this: a= \frac{k}{9b+4}
