Which is the slope of a line that is perpendicular to the line that passes through the points (-9, -4) and (3, 4)?

3/2

Step-by-step explanation:

First find the equation of the line passing through the two given points (-9, -4) and (3, 4).  The change in x (the 'run') is 3 - (-9), or +12.  The change in y (the 'rise') is 4 - (-4), or 8.  Thus, the slope of this line is

m = rise/run = 8/12, or m = 2/3.

A line perpendicular to this one has a slope that is the negative reciprocal of the slope we just found:

m = -1 / (2/3) = -3/2

the correct answer is 1: 2

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
