Final answer:
To rewrite the equation in slope-intercept form, we solve for y and isolate it on one side. The slope-intercept form of the equation is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 4 and the y-intercept is (0, -3).
Step-by-step explanation:
To rewrite the given equation in slope-intercept form, we need to solve for y and isolate it on one side of the equation. Starting with 12x - 3y = 9:
- Subtract 12x from both sides: -3y = -12x + 9
- Divide every term by -3 to solve for y: y = 4x - 3
So, the slope-intercept form of the equation is y = 4x - 3. From this, we can determine that the slope is 4 and the y-intercept is (0, -3).
