Which of the following equations represents the line that passes through the point (1, –1) and is perpendicular to the line below?

The graph of the line would be y + 1 = m(x - 1) in which m is the slope. That slope would be the opposite and reciprocal of the one on the graph.

Step-by-step explanation:

To find the equation, start with the base form of point slope form and insert all known information.

y - y1 = m(x - x1)

y + 1 = m(x - 1)

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
