Answer:
1: x = -8 . A vertical line will always be in the form "x=". In this case, x is -8.
2: Since the slope is zero for a horizontal line, we can use the slope-intercept form, y = mx + b to write an equation for it. Since m = 0, it becomes y = b.
3: The equation of a vertical line always takes the form x = k, where k is any number and k is also the x-intercept . (link) For instance in the graph below, the vertical line has the equation x = 2 As you can see in the picture below, the line goes straight up and down at x = 2.
4: In a horizontal line the y value remains the same.
In the point ( -4.-6 ) the y value is -6. the point notation is always written as ( x, y).
The y value throughout the line must be -6 so the equation must be
y = -6
