Question

Find the equation of the line that contains the point (-1, 2) and is perpendicular to the line 2x + 4y = -2.

Answer 1

M*=2
so
M=-1/2

since M=(y-y1)/(x-x1)
so
-1/2=(y-2)/(x+2)
so
2y-4=-x-2
so
2y=2-x

Answer 2

ok so what I am confused is how you figure out M

Answer 3

M is the slope of the 1st line
M* is the slope of the 2nd lines at which the 1st line is Perpendicular To.

Answer 4

ok i understand thank you
