11) Give the slope-intercept form of the equation of the line that is perpendicular to 5x + 2y = 12 and contains the point (2, 3).
12) Tell whether the lines are parallel, perpendicular, or neither.
The line through (-3, 2) and (4, 6) and the line through (-5, 7) and (-9, 14)
13) Which two lines are parallel?
3x + y = -2
2y – 6x = 4
2y = -6x – 8
