Answer:

The answer to your question is the letter C.

Step-by-step explanation:

Data

P (-2 , 4)

m = 5

Process

1.- Write the equation of the line

             y - y1 = m(x - x1)

x1 = - 2         y1 = 4

2.- Substitution

            y - 4 = 5(x + 2)

3.- Simplification

            y - 4 = 5x + 10

- Solve for y

           y = 5x + 10 + 4

           y = 5x + 14       This is the equation of the line in the point-slope form.
