Dane rownanie prostej napisz w postaci kierunkowej

a)2x−5y+15=0

b)2x−3y−6=0

c)√3x+3y−1=0

d)3√2x+6y−1=0

Answer 1

a)2x−5y+15=0

-5y = -2x -15 /:(-5)

y =2/5 x + 3

 

b) 2x−3y−6=0

-3y = -2x+6 /:(-3)

y= 2/3 x - 2

 

c)√3x+3y−1=0

3y =-√3x+1 /:3

y= -√3/3 x+1

 

d)3√2x+6y−1=0

6y= -3√2x+1/:6

y= - √2/2 x+1/6
