Question

1. y = -1

find the intercepts for the graph.

2. x = -1

find the intercepts for the graph.

Answer 1

1. y = -1 is a horizontal line and intercepts the y axis at (0,-1). Because it is horizontal it does not intercept the x-axis.

2. X = -1 is a vertical line that intercepts the x axis at (-1,0). Because it is vertical it does not have a y-intercept

Answer 2

y=-1 is a horizontal line parallel to the x axis at y = -1.

x = -1 is a vertical line parallel to the y axis at x = -1
