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

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
