Quiz: Quiz 4 for Sections 2.1-2.4 Time Remaining: 00 42 16 Submit This Question: 1 pt 13 of 15 (0 complete) This Quiz: 15 pts po Write an equation for line L in point-slope form and slope-intercept form. L is perpendicular to y = 4x Write an equation for line L in point-slope form (Simplify your answer. Use integers or fractions for any numbers in the equation.) Write an equation for line L in slope-intercept form. (Simplify your answer. Use integers or fractions for any numbers in the equation.)Explanation / Answer
L is perpendicular to y = 4x
slope of perpendicular lines are negative reciprocal of each other
slope of y = 4x is 4
slope of perpendicular line = -1/4
passing through (-1, -4)
point slope form of equation is
y + 4 = -1/4 ( x + 1 )
slope intercept form of equation is
y = -1/4 x - 1/4 - 4
y = -1/4 x - 17/4
