Question

Which function has the same y-intercept as the function

y = ſc – 3?
2 + 4y = 12
- x + 3y = 6
6x – 7y= 21
x + 3y = -3

Answer 1

The answer is 6x-7y=21

In order to find this answer you need to convert the answer choices into y intercept form by isolating the y variable to one side of the equation.
6x-7y=21
-7y=-6x+21
y=6/7x-3
As you can see when you change the form of this equation, the y intercept is -3.
