Question 459383
Question 1)Find the equation of the line which passes through the point (0,-5)and is parralel to y=8x-3 

slope of line = 8 

(y+5) = 8(x-0)

=> y = 8x -5  (equation of required line in slope intercept form ) 


 
Question 2) Find the equation of the line which is perpendicular to y=5x-7 and passes through the point (0, -2) 

slope of line = 5 , slope of required line = -1/5 

(y +2) = -1/5 (x-0)

=> y + 2 = -x/5 

=> y = -x/5  - 2

(equation of required line in slope intercept form )
