Can somebody help me with this?

B) Only (-2, 9)

Step-by-step explanation:

To find out which of the given options is the solution to the linear equation, y = -2x + 5:

We can substitute the values of the given options to see whether they provide a true statement.

A) (2, -9):

y = -2x + 5

-9 = -2(2) + 5

-9 = -4 + 5

-9 = 1 (False statement. Therefore, this option is not included as a solution).

B) Only (-2, 9):

9 = -2(-2) + 5

9 = 4 + 5

9 = 9 (True statement. Thus, (-2, 9) is a solution to the given linear equation).

We no longer have to test options C and D because we already tested (2, -9) and determined that it's not a solution.

Therefore, the correct answer is option B) Only (-2, 9).

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
