Answer:

-18

Step-by-step explanation:

Between any number (in this case -9) and letter (in this case x) in an algebraic equation, there is an invisible multiplication.

-9 × x

the question states that x = 2, so we can substitute the 2 into the equation

-9 x 2

a positive number multiplied by a negative number always gives a negative number, and 9 x 2 = 18

∴ the answer to this equation = -18

Answer:

y = 8x - 11

Step-by-step explanation:

Using the equation

y - y1 = m (x - x1)

y - 5 = 8 (x- 2)

y - 5 = 8x - 16

Subtract the 5

y = 8x - 11
