Finding Slope of Parallel Lines

Question

What is the slope of a line parallel to the line whose equation is x−y=−1

Answer 1

x-y = -1

x-y + 1 = 0

x+1 = y

y = x+1

the slope of the line and ANY line parallel to it shall be ONE (1)

Answer 2

x − y = −1

First, convert the equation to "slope-intercept" format: y = mx + b, where m is the slope and b is the y intercept.

-y = -x - 1

so:

y = x + 1 Thus the slope is 1. A parallel line will have the same slop.

Answer 3

The slope of the given line is 1 and therefore, the slope of any line parallel to it will be 1.
