Also, how do I write an equation for a line that has a y-intercept of -1 and is perpendicular to a line that has a slope of -1? Thanks for your help!Answer by kiru_khandelwal(79)   (Show Source): You can put this solution on YOUR website!Equation of the line is y = mx + c where m is the slope and c is the y intercept so if slope is 3 and y intercept is also 3 equation of the line will be y = 3x + 3 If a line is perpendicular to a line with slope m, then the slope of that line will be -1/m So if the slope of a line be -1 then slope of the line perpendicualr will be 1 y intercept is -1 so equation of the line will be y = 1x -1 => y = x-1
