HELP ME WITH THIS SET OF QUESTIONS!!
 1.Write an equation in point-slope form for the line that has a slope of 9/4 and contains the point (3, −4).
 2. Identify the equation in slope-intercept form for the line containing the points (3, 5) and (2, −5).
 3. Write an equation in slope-intercept form for the line perpendicular to y = −4x + 1 that passes through the point (−7, 1).
 4. Describe the transformation from the graph of f(x) to the graph of g(x). 
 f(x) = 4x, g(x) = −4x
 5. Identify the equation that describes the line in slope-intercept form. 
 slope = 3, point (−2, −4) is on the line
