Find the equation of the line described, and express your answer in the specified form.
-Perpendicular to the line -4x + 3y = 5; passes through the point (0, -1); standard form
A)-4x + 3y = -3
B)3x + 4y = -3
C)-4x + 3y = 4
D)3x + 4y = -4

Question

The slope of the line -4x + 3y = 5 is 4/3. A line perpendicular to it will have a slope of -3/4. Using the point (0, -1) and the slope -3/4, the equation in point-slope form is y + 1 = -3/4(x - 0). Converting to standard form gives 3x + 4y = -4.
