6x-5y=9.....
Slope = 2.400/2.000 = 1.200
x-intercept = 9/6 = 3/2 = 1.50000
y-intercept = 9/-5 = -1.80000
So -18+1.8b=-27
Slope = 10
x-intercept = 15/10 = 3/2 = 1.50000
b-intercept = 15/-1 = -15.00000

Answer: Choice A

Explanation:

\frac{h}{6} = quotient of h and 6

\frac{h}{6}+7.8 = 7.8 more than the quotient of h and 6

\frac{h}{6}+7.8 = w

The "is" often refers to "equals" in math translation problems like this.

Another example "h is 10" means "h = 10".
