The lines below are parallel. if the slope of the green line is -4. what is the slope of the red line M=

a.-4

b.-1/4

c.1/4

d.4

a

Step-by-step explanation:

if the two lines are parallels they have to have the same slope

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.
