Question

PLEASE HELP!!! 15 PTS FOR THIS!! (Please show work also) Convert y=3x-14 (slope intercept form) to standard form Convert y-6=-1/3(x-9) (point slope form) to standard form Convert 3x+y=9 (standard form) to slope intercept form

Answer 1

Explanation:

y=3x-14

standard form : 3x-y=14 ( move variable together on one side )

convert y-6=-1/3 (x-9) to standard form :

first : y-6 = -1/3 x -1/3(-9)

y-6=-1/3 x +9/3

y-6=-1/3x+3

y+1/3x =3+6

y+1/3x=9 ( common denominator)

(3y+x)/3=9 ( cross multiplication)

3y+x=3(9)

3y+x=27

Convert 3x+y=9 (standard form) to slope intercept form (y=mx+b)

3x+y=9

y=-3x+9
