Question

write the equation of a line perpendicular to m= -1/3, (-2,-5)

Answer 1

A perpendicular line is going to have the negative reciprocal slope.
So, the negative reciprocal slope of -1/3 is 3/1 or just 3.

y - y1 = m(x - x1) using slope 3 and points (-2,-5)
y - (-5) = 3(x - (-2)
y + 5 = 3(x + 2)
y + 5 = 3x + 6
y = 3x + 6 - 5
y = 3x + 1
