through: (4, -1), parallel to y = x - 1

The answer to your question is            y = x - 5

Step-by-step explanation:

Data

Point = (4, -1)

line ║ to y = x - 1

Process

1.- Find the slope. The slope is the coefficient of the x.

                y = 1x - 1

     slope = m = 1

2.- Identify the values x1 and y1

             x1 = 4     y1 = -1

3.- Find the equation of the line

             y - y1 = m(x - x1)

-Substitution

           y + 1 = 1(x - 4)

-Solve for y

           y + 1 = x - 4

          y = x - 4 - 1

-Result

           y = x - 5
