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)

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)
