A line has a slope of -3/2 and a y-intercept of 6. what is the equation of the line in standard form?

• 3x-2y=2

• 3x + 2y = -12

• 3x + 2y = 12

• 3x - 2y = -12

• g(x) = 4f(x)

• g(x) = -4(f(x)

• Not a function, linear

• 2

• -1

• 7

• -5

If y varies directly as x, and y = 16 and x = 4, what is the value of y when x = 15?
