What is the slope-intercept form of 6x - 2y - 4 = 0?
Correct answer: C. y = 3x-2
- A. y=6x-2
- B. y = 3x + 2
- C. y = 3x-2
- D. y = −6x - 4
Explanation
The correct answer is C. The slope-intercept form of the equation of a line states that y=m x+b. To find the slope-intercept form of the equation 6x-2y-4=0, you must isolate y on the left side of the equation as follows: 6x-2y-4=0 -2y=-6x+4 th -2y-4--6x y=3x-2 If you selected answer choice D, you probably forgot to switch the signs when dividing by 2. It is crucial to multiply all terms on both sides of the equation to arrive at a correct answer.
