Answer:

LET NUMERATOR BE X.

SINCE ,

DENOMINATOR+NUMERATOR

=3* NUMERATOR+1

D+X=3X+1

D=2X+1

THEREFORE , X/2X+1=ORIGINAL FRACTION.

X+1/2X+1=1/3

3(X+1)=2X+1

3X+3=2X+1

X= -2

THEREFORE,D=2X+1=-4+1

=-3

THEREFORE,

FRACTION=-2/-3

=2/3

Y = Mx + b

Where Mx is the slope and b is they y intercept

The slope is 2 and the y intercept is -6

We know the y intercept cause it’s written (x,y) and -6 is in the y value spot.

So just plug in the numbers and you get

Y= 2x + -6
