How do you write an equation of a line passing through (-4, -3), perpendicular to 4x + y=7?
The equation is
A line perpendicular to another will have a slope that's the negative reciprocal of the other.
Let's make the initial equation into slope-intercept form
The slope here is
The slope of the line perpendicular will be
By point-slope form, the equation of the line perpendicular is:
