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

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

Write the equation in point-slope form for the line that contains the points
(-2, -3), (4, 3)

• y - 3 = 1(x - 2)

• y + 3 = 1(x + 2)

• y -3 = -1(x + 2)

• y + 3 = -1(x - 2)

Write the equation in point-slope form for the line that contains the points
(3, -5) and (5, - 1)

• y - 5 = 2(x + 3)

• y + 5 = 2(x - 3)

• y - 3 = 2(x + 5)

• y + 3 = 2(x - 5)

Write the equation of a line parallel to the one pictured through the point (3,1) in point slope form.
(HINT: PARALLEL LINES HAVE THE SAME SLOPE)

• y - 1 = 1/2(x - 3)

• y + 1 = 1/2(x + 3)

• y - 1 = - 1/2(x - 1)

• y + 1 = - 1/2(x + 3)

Write the equation of a line perpendicular to the one pictured through the point (3,1) in point slope form.
(HINT: PERPENDICULAR LINES - FLIP AND SWITCH)

• y - 1 = 1/2 (x - 3)

• y + 1 = 2 (x + 3)

• y - 1 = - 1/2 (x - 1) 

• y - 1 = - 2 (x - 3)
