#### Answer:

#### Explanation:

#x=-1" cannot be written in "color(blue)"slope-intercept form"#

#"this line is a special case in that it is a vertical line and"#

#"parallel to the y-axis passing through all points in the"#

#"plane with an x-coordinate "=-1#

#"because it is vertical it's slope is undefined and it does"#

#"not intersect the y-axis"#

#"see graph of "x=-1" below"#

graph{(y-1000x-1000)=0 [-10, 10, -5, 5]}
