Which of these is point-slope?

For the equation

y + 3 = -4(x - 2),

which of the following is true?

• The line has m = −4 passing through the point (2, -3)

• The line has m = 4 passing through the point (3, −2)

• The line has m = 3 passing through the point (-4, -2)

• The line has m = −4 passing through the point (−3, 2)
