Find equati

Answer :

Given equation of line is x – 7y + 5 = 0



Which is of the form y = mx + c, where m is the slope of the given line.


slope of the given line is 1/7


Slope of the line perpendicular to the line having slope m is -1/m


Slope of the line perpendicular to the line having a slope of 1/7 is = -7


Equation of line with slope -7 and x intercept 3 is given by y = m(x – d)


y = -7 (x – 3)


y = -7x + 21


7x + y = 21
