Final answer:
To rewrite the equation in slope-intercept form and determine the slope and y-intercept, subtract 12x from both sides of the equation, then divide both sides by -3. The slope is 4 and the y-intercept is (0, -3).
Step-by-step explanation:
To rewrite the equation 12x - 3y = 9 in slope-intercept form, we need to isolate the variable y. First, subtract 12x from both sides of the equation to get -3y = -12x + 9. Then, divide both sides by -3 to obtain y = 4x - 3. Therefore, the slope-intercept form of the equation is y = 4x - 3. The slope of the equation is the coefficient of x, which is 4, while the y-intercept is the constant term, which is (0, -3).
