What is the equation of a vertical line passing through the point (−4, 7)

kamibug · Answer

The equation of a vertical line always starts with "x=" because it only passes through one point on the x-axis. Just take the x-coordinate from the point you are given. :) 
The equation for this line would be x = -4.

On the graph of the equation 6x − y = −1, what is the value of the y-intercept?

kamibug · Answer

The y-intercept means where the line crosses the y-axis. Any point that touches the y-axis has a x-coordinate of 0. So, just plug in 0 for x in the equation and solve for y! :) Think you got this one from here?

anonymous · Answer

yintercept is  -1?

kamibug · Answer

6(0) - y = -1
- y = -1
   y = 1 <-- You have to get the opposite b/c we are looking for +y, not -y. :)
