Question 829417: )Find the equation of the line (in y = mx + c form) that:
a)is perpendicular to the line with equation y = 3x + 1, passing through (−3, 6)
b)is parallel to the line with equation y = 2/5x-9, passing through (4, −7)
c)is parallel to the line with equation 3x + 6y = 8, passing through (2, 2)
d)is perpendicular to the line with equation −6x + 7y − 2 = 0, passing through (4, 0)
e)has gradient 2, passing through the intersection of the lines with equations y = 3x − 5 and y = −2x + 5
f)has gradient -3/4, passing through the intersection of the lines with equations x + 4y = −14 and −5x + 2y = 4.
