Slope Intercept, Point Slope, Standard Form

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

• y - y₁ = m(x - x₁)

• Ax + By = C

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)
