Write an equation in point-slope form of the line that passes through the given point and has the given slope: (–2, –1); m = –3

• y - 1 = - 3 (x - 2)

• y +2 = - 3 (x + 1)

• y + 2 = - 3 (x + 1)

• y + 1 = - 3 (x + 2)

Write an equation in point-slope form of the line that passes through the given point and has the given slope: (1, 3); m = 5

• y - 3 = 5 (x - 1)

• y - 1 = 5 ( x - 3)

• y + 3 = 5 (x + 1)

• y + 1 = 5 ( x + 3)

Identify the slope and ordered pair from the equation: y – 3 = –2 (x + 4)

• m = - 2 ( 3, - 4 )

• m = - 2 ( - 4, 3 )

• m = 2 ( - 4, 3 )

• m = 2 ( 3, - 4 )

Identify the slope and ordered pair from the equation: y – 4 = – (x + 2)

• m = 1 ( - 2, 4 )

• m = - 1 ( - 2, 4 )

• m = - 1 ( 4, - 2 )

• m = - 1 ( 2, - 4 )
