Answer:
Step-by-step explanation:
y=-1 is a horizontal line going through y=-1. x=-1 is a vertical line going through x=-1.
y=-1 has a slope of zero. the y-intercept is -1.
x=-1 has no slope. the slope is undefined. there is no y-intercept.

Answer:
y = -2x + 1
Step-by-step explanation:
<u>Formulae:</u>
<u />
Slope: 
- m = slope
- y₂ = second y-value
- y₁ = first y-value
- x₂ = second x-value
- x₁ = first x-value
Point-slope form: 
- y₁ = first y-value
- m = slope
- x₁ = first x-value
Slope-intercept form: 
- m = slope
- b = y-intercept value
