m= 5

(2, 4)

• y - 2= 5(x - 4)

• y - 4= 5(x - 2)

• y- 5 = 4(x - 2)

• y - 2 = 4(x - 5)

m= 3

(1, 7)

• y - 7 = 3( x - 1)

• y - 1 = 3( x - 7)

• y - 3 = 3( x - 1)

• y - 1 = 7( x - 3)

Which of these represents point-slope form of a linear equation?

m=4

(2, 2)

• y- 2 = 4( x - 2)

• y- 4=4(x - 2)

• y- 2= 2( x - 2)

• y + 2 = 4(x + 2)

m=6

(2, 7)

• y - 7 = 2( x - 6)

• y - 7 = 6( x - 2)

• y - 7 = 6( x + 2)

• y - 7 = 3( x - 6)
