Can you help me with Part I, II, III, and IV? Thank you !

4. Line p contains point (6, -5) and is perpendicular to line q. The equation for line q is y= 3x+ 5. Write an equation for line p. Part I: Find the slope of line q. (1 point) Part II: Find the slope of line p. (Write the negative reciprocal of the slope you found in Part I.) (1 point) Part III: Use the point given for line p and the slope you found in Part II to write an equation for line p in point-slope form: y - y. - m(x - x.). (1 point) Part IV: Use your equation from Part III to write an equation for line p in slope- intercept form: y - mx + b. Show your work. (1 point)
