 Question 426982: Write the slope-intercept equation for the line that passes through (-7, 6) and is perpendicular to -7x + 9y = -2 Please show all of your work. Answer by mananth(12270)   (Show Source): You can put this solution on YOUR website!-7 x + 9 y = -2 Find the slope of this line 9 y = 7 x + 2 Divide by 9 y = 7/9 x 0.22 Compare this equation with y=mx+b slope m = 0.78 The slope of a line perpendicular to the above line will be the negative reciprocal m1*m2=-1 The slope of the required line will be -1.29 m= -1.29 ,point (-7,6) Find b by plugging the values of m & the point in y=mx+b 6=9+b b=-3 m=-1.29 The required equation is y=-1.29 x-3
