Write an equation of a line with the given slope and y-intercept. m = –2, b = 4

Step-by-step explanation:

The given data is

Where is the slope of the line and is the y-intercept. So, basically this line has a slope of -2 and y-intercept at 4.

To find its equation, we use the slope-interception form

Then, we replace each given value

Therefore, the equation for the given line is

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)
