Line p goes through points (-2,6 ) and ( 4,-3 ). What is the equation of line p?

y = mx + b

m = (-3 - 6)/(4 + 2) = -9/6 = -3/2

y = (-3/2)x + b

6 = (-3/2)(-2) + b

6 = 3 + b

b = 3

y = (-3/2)x + 3

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
