SOLUTION: What formula do i use to solve six problems, who's directions say write the slope-intercept form of an equation of the line that passe through the given point and is perpendicular

You can put this solution on YOUR website!
Yes, you do it exactly the same way except that when you do parallel lines, the slopes are equal, but when you do perpendicular lines, the slopes are the negative reciprocal of each other. In other words, if is the slope of line and is the slope of line , is perpendicular to if and only if

For your first problem:
(-2,-2) , the slope is , so the slope of the perpendicular has to be 3.







Let me know if you need more help.
