Question

What is the equation of the line that passes through the point (2, 3) and is perpendicular to the line y = –x – 3?

Answer 1

Equation of the line is y=-x-3
Its slope m=-1
Slope of line perpendicular to above line=-1/m=-1/-1=1
Equation of line with slope 1 and passing through (2,3) is
y-3=1(x-2)
y=x-2+3
Required eq. is y=x+1

Answer 2

thanks so much
