Question

Choose the slope-intercept equation of the line that passes through the point (-5, -1) and is perpendicular to y = x + 2.

Answer 1

Use the opposite reciprocal of original slope for perpendicular equations and plug it into point slope form which is y-y1=m(x-x1)
Opposite reciprocal of 1 is -1
So now plug in points and slope
y-(-1)=-1(x-(-5)) this equals y+1=-x-5
in normal line format answer would be
y= (-x)-6
