Find the slope and y-intercept of the equation of the line. -3y - 9x = -12
A)slope: 9; y-intercept: -12
B)slope: -12; y-intercept: 9
C)slope: 9; y-intercept: -3
D)slope: 4; y-intercept: -3
E)slope: -3; y-intercept: 4

To find the slope and y-intercept, we first solve the equation for y in terms of x: -3y = 9x + 12 => y = -3x - 4. The slope is the coefficient of x, which is -3, and the y-intercept is the constant term, which is -4. However, there's a mistake in the options provided; none correctly matches the calculated slope and y-intercept. The closest option based on the slope is E, but it incorrectly states the y-intercept as 4 instead of -4.
