Answer:

  • See below

Step-by-step explanation:

As per the question we have:

  • The y - intercept is b = -1
  • The slope has same angle with x- and y - axis.

This can be a function with the slope of m = 1 or m = - 1 as these lines must be perpendicular to each other and make 90°/2 = 45° or 45° + 90° = 135° angle with the x- or y- axis.

So the lines could be:

  • y = x - 1 or
  • y = -x - 1

Lines must be perpendicular to each other as they are cutting at y intercept -1

Slope intercept form of line

for slope -1

  • y=-x-1

For slope 1

y=x-1
