A line passes through the point (4, –3) and has slope m = 1. Find the equation in point–slope form.

y + 3 = x + 4

y + 4 = x - 3

y - 4 = x - 3

y + 3 = x - 4

Respuesta :

Answer:

The expected answer is ...

  y +3 = x -4

Step-by-step explanation:

The line with slope m through point (h, k) can be written in point-slope form as ...

  y -k = m(x -h)

For (h, k) = (4, -3) and m=1, the filled-in form is ...

  y +3 = x -4

___

It happens that the same line can be described by ...

  y +4 = x -3 . . . . . matches the second choice

because that line also goes through the point (3, -4).
