Hi. I am having some issues with this one. Give the equation of the line that is perpendicular to the line y=x+6 and passes through point (0,-4). Thank you so very much!!!
Answered by Reiny
The slope of y = x+6 is 1
so the slope of the perpendicular is -1

new equation:
y = -x + b , but (0,-4) lies on it and it is the y-intercept, so new equation....

y = -x - 4
